Abstract：

We　present　a　nonlinear-mirror　(NLM)　mode-locked　crystal　waveguide　laser.　By　adding　nonlinear　crystals　into　traditional　NLM　devices,　the　fourth　harmonic　is　generated　to　form　loss　modulation,　which　suppresses　the　Q-switching　instability　of　mode-locked　lasers　and　achieves　the　optimal　equivalent　transmittance.　The　NLM　mode-locked　laser　delivers　∼30　W　average　power　with　a　repetition　rate　of　32.2　MHz　and　a　pulse　width　of　950　fs.　It　is　revealed　that　this　novel,　to　the　best　of　our　knowledge,　design　with　simple,　robust,　and　reliable　structure　has　a　great　potential　in　the　development　of　high-power　mode-locked　laser.　©　2023　Optica　Publishing　Group.
