Abstract ：
To study the transmission ability of hollow-core anti-resonance fiber, a mid-infrared laser transmission experiment was carried out using a self-made nodeless hollow-core anti-resonance fiber from 2. 6 mu m to 4. 35 mu m spectral region. The fiber cladding consists of seven silica capillary tubes, the average wall thickness is 800 nm, the outer diameter of the fiber is 365 mu m, and the core diameter is 115 mu m. A tunable mid-infrared source was used as a broadband light source. The laser propagation capability of the fiber at 2. 60 mu m, 3. 27 mu m, 3. 41 mu m, 3. 80 mu m, 4. 08 mu m, 4. 21 mu m, and 4. 35 mu m was tested. And the transmission loss at this spectral region of the fiber was measured. Results show that the fiber can realize low-loss light guide from 2. 6 mu m to 4. 08 mu m hand, with the lowest transmission loss of 0. 037 dB/m at 3. 27 mu m. The transmission loss of the fiber is 3. 200 dB/m at 4. 08 mu m and 0. 788 dB/m at 4. 35 mu m, where the attenuation of hulk silica is 1000 dB/m and 3000 dB/m. respectively. Hollowcore anti-resonance fiber has great potential in the application of mid-infrared laser flexible delivery.

Abstract ：
A yttrium aluminosilicate fiber with a Yb doping concentration of 4.53 wt.% was fabricated by powder-in-tube method, in which the preform core was Yb:YAG ceramic nanopowders synthesized by co-precipitation method. Compared with the method of using YAG crystal rod as fiber core, the fiber composition design can be more flexible and a series of crystal rod processing technology can be circumvented. The absorption coefficient of the Yb-doped YAS fibers was measured 28.4 dB/cm at 976 nm. A single-frequency fiber laser was constructed with the YAS fiber length of 1cm. To our knowledge, this is the first time that rare earth (RE) doped YAS fiber prepared by powder-in-tube method was used in fiber laser.

Abstract ：
Objective Since the first observation of light guidance in a hollow-core optical fiber ( HCF) in 1999, the development of the HCF has attracted much attention in the last two decades. The presence of the microstructure in the cladding allows the HCF to confine most of the light energy in the hollow core of the fiber. This makes it possible to break the limitations of conventional solid-state fibers with the benefits of low nonlinear effects, high damage thresholds, low transmission losses, low latency, etc. Especially, the breakthrough results in dramatic loss reduction achieved by a hollow-core anti-resonant fiber (HC-ARF) make this kind of fiber become one of the most remarkable and promising fiber types nowadays. In the present study, a 5-tube nested hollow-core anti-resonant fiber (Nested HC-ARF) is investigated, which exhibits outstanding optical performances in terms of O. 38 dB/km attenuation at around 1550 nm and excellent modal purity. Methods The Nested HC-ARF is fabricated using the modified stack-and-draw method, in which the 5 nested capillaries are first stacked and fused inside a jacket tube and then drawn to the intermediate canes. Subsequently these canes are scaled down to fiber dimensions using a conventional cane-in-tube process. The thickness of the inner and outer tubes is carefully controlled by holding the differential pressure to satisfy the anti-resonance conditions at the designed operational wavelength. Finally the uncontrolled distortions are maximally suppressed by drawing the fiber under a relatively low furnace temperature and very high drawing tension. Results and Discussions The fundamental transmission band of the fabricated Nested HC-ARF starts at around 1265 nm and extends beyond 1700 nm. The average attenuation value of 0.38 dB/km is achieved from 1545 nm to 1660 nm, which covers the optical telecommunication C and L bands. The uncertainty shown by the grayed region arises from cleave-to-cleave variability. Loss peaks appearing in the short wavelength edge of the transmission band from 1340 nm to 1500 nm can be attributed to H2O absorption. By proper argon gas purging, these absorption-induced loss peaks can be greatly suppressed. In addition, we estimate the LP. mode loss of similar to 2. 96 dB/m by cutback measurements with the spatial and spectral imaging technique. This is equivalent to the higher-order mode (HOM) suppression ratio of our Nested HC-ARF exceeding 38 dB, which is guaranteed by the resonant coupling provided by the well-designed fiber structure. It confirms that the combination of suitable excitation, intrinsic HOM loss discrimination and length of the fiber does indeed lead to high modal purity and effective single-mode guidance. Conclusions We have fabricated a 5-tube Nested HC-ARF with an outstanding optical performance. This Nested HC-ARF possesses an average attenuation value of 0. 38 dB/km from 1545 nm to 1660 nm. The excellent modal purity of the fiber is also experimentally verified. We believe that this fiber is attractive to many applications such as long-haul data transmission.

Abstract ：
A high-average-power, high-pulse-energy picosecond chirped pulse amplification (CPA) laser system based on an extra-large-mode-area (XLMA) triple-clad fiber (TCF) was demonstrated. The ultrashort pulses, generated from all-fiber mode-locked oscillator, stretched and then were pre-amplified to 10 W through a series of fiber power amplifiers. Subsequently, the average output power was amplified to 620 W corresponding to a pulse energy of 0.62 mJ via XLMA TCF. Additionally, the amplified pulses were compressed to a pulse duration of 7.6 ps with an average power of 423 W and a compression efficiency of 68.2%. The ultrashort laser is a promising light source for application of water-guided laser processing, albeit with a beam quality factor of 20 and 21 along two orthogonal axes.

Abstract ：
We present a hybrid chirped pulse amplification (CPA) laser system based on Yb-doped fiber and Yb:YAG thin rod. The laser system demonstrates a novel approach to generate high average power up to the 100-W level by using a Yb:YAG thin rod without pump guiding at room temperature. A Yb-doped all-fiber laser with an output power of 7 W and a repetition rate of 1 MHz is amplified to an output power of 126.2 W in simple and compact two-stage amplifiers consisting of a single fiber crystal (SCF) and a Yb:YAG thin rod. To the best of our knowledge, this is the highest output power of Yb:YAG thin-rod amplifier with good beam quality obtained without pump guiding at room temperature. After using a thin-film polarizer (TFP) to remove the thermal depolarization, a linearly polarized ultrashort pulse laser with an average power of 115.2 W is obtained. An output power of 80.6 W with a pulse width of 580 fs is achieved after pulse compression. The central pulse contains 84.1% of the total pulse energy, corresponding to a pulse peak power of 116.9 MW.

The power handling capability of the Nested HC-ARF is also demonstrated in this work. Pulses of 75 W, 160 ps from the thulium-doped fiber laser are delivered using a 6-m-long fabricated Nested HC-ARF. The tested fiber is coiled into a 20 cm bending radius and achieves a coupling efficiency of 86.7%. The maximum average power of 60.5 W is transmitted through our Nested HC-ARF in a robust single-mode fashion without introducing any damage to the input and output fiber end-faces, which demonstrates the superior ability of such a fiber for high-power laser delivery.

Abstract ：
A dispersion-managed, figure-of-9, mode-locked ultrafast Yb-doped fiber laser is presented in this letter. The laser cavity employs a chirped fiber Bragg grating with a proper anomalous dispersion for intra-cavity dispersion compensation. The laser with large normal net dispersion delivers an output with maximum average power of 20 mW and pulse duration of 5.50 ps at the repetition rate of 39.1 MHz, and the pulse can be dechirped to 228 fs. While net dispersion of cavity is very close to zero, the laser delivers an output with an average power of 12 mW at the repetition rate of 47.3 MHz, and the pulse duration is 1.86 ps, which can be dechirped to 175 fs. The whole cavity is very compact and environmentally stable, for its all-polarization-maintaining and all-fiber structure.

Abstract ：
As laser technology has gradually been integrated into our life, it serves as a promising tool for artistic creation. By means of advanced science and technology in this field, we expect to improve the design of traditional arts and crafts to an innovative level. In this paper, we presented a multifunctional laser paintbrush for creating traditional artistic pictures on metallic surface. We demonstrated that our laser paintbrush has three basic functions: coloring, erasing and rewriting. Firstly, the process of laser-induced coloration on titanium surface were investigated experimentally and theoretically. Then, the influences of laser parameters on laser-induced coloration were quantitatively evaluated and this color durability in terms of time, chemical and environ-mental resistance was examined. Moreover, we proposed using ultrafast pulsed laser to selectively erase the colored areas in ethanol and nitrogen atmosphere. We found that our laser paintbrush had high erasing quality on the colored surface. Rewriting in the erased fields can increase the saturation and lightness of colors. Finally, with this multifunctional laser paintbrush, we successfully created traditional artistic pictures with different colors on metals with this multifunctional laser paintbrush.

Abstract ：
We demonstrated an ultra-low noise polarization-maintaining (PM) single frequency fiber laser (SFFL) at 2 mu m. By suppressing the pump relative intensity noise using a feedback loop control, the RIN and frequency noise of the SFFL are simultaneously reduced, and the reduction is about 3 - 15 dB and 3 - 8.4 dB, respectively. After two stage Tm3+-doped PM fiber amplifier, the output power reached about 5.2 W. Meanwhile, the frequency noise almost has no increases, which is still below 100 Hz/root Hz after 13 Hz. And the frequency-tunable range is approximately 2 GHz with frequency response of 46 MHz/V.

Abstract ：
High-power fiber lasers have experienced a dramatic development over the last decade. Further increasing the output power needs an upscaling of the fiber mode area, while maintaining a single-mode output. Here, we propose an all-solid anti-resonant fiber (ARF) structure, which ensures single-mode operation in broadband by resonantly coupling higher-order modes into the cladding. A series of fibers with core sizes ranging from 40 to 100 mu m are proposed exhibiting maximum mode area exceeding 5000 mu m(2). Numerical simulations show this resonant coupling scheme provides a higher-order mode (mainly TE01, TM01, and HE21) suppression ratio of more than 20 dB, while keeping the fundamental mode loss lower than 1 dB/m. The proposed structure also exhibits high tolerance for core index depression.
