We　report　an　all-fiberized　chirped　pulse　amplification　system　without　any　bulk　devices.　The　stretcher　and　compressor　are　chirped　fiber　Bragg　gratings　inscribed　in　a　6/125　mu　m　single-mode　fiber　and　a　30/250　mu　m　large-mode-area　fiber.　The　fabrication　system　of　chirped　fiber　Bragg　gratings　was　designed　and　built　by　ourselves.　The　width　of　the　linear　exposure　spot　was　controlled　according　to　the　different　fiber　sizes　to　improve　the　fabrication　quality,　and　the　parameters　of　chirped　fiber　Bragg　gratings　were　fine-tuned　during　the　fabrication　to　achieve　the　overall　system＇s　spectral　matching.　Two　fiber　circulators　with　the　same　fiber　sizes　as　the　chirped　fiber　Bragg　gratings　were　employed　to　auxiliarily　achieve　the　pulse　stretching　and　compression.　The　dispersion　accumulations　provided　by　the　stretcher　and　compressor　are　129.8　ps　and　90.8　ps.　The　power　amplifiers　were　composed　of　the　two-stage　10/130　mu　m　fiber　pre-amplifier　and　the　30/250　mu　m　fiber　main　amplifier.　The　proposed　chirped　pulse　amplification　system　with　no　spatial　light　is　the　true　sense　of　an　all-fiberized　chirped　pulse　amplification　structure　and　shows　the　main　trend　in　development　of　ultrashort　pulse　fiber　lasers.
