摘要：

We　demonstrated　a　femtosecond　green　laser　operating　at　532　nm　by　frequency　doubling　of　a　1　μm　linearly-polarized　all-fiber-integrated　femtosecond　chirped　pulse　amplification　system.　The　1-μm　broad-spectrum　seed　with　a　3　dB　spectral　bandwidth　of　11.3　nm　was　founded　by　dispersive　wave　technology.　The　average　power　was　scaled　up　to　6.5　W　by　two　stage　ytterbium-doped　fiber　amplifier　and　the　pulse　duration　was　compressed　to　371　fs　through　grating　pair　compressor.　Finally,　a　maximum　green　laser　power　of　1.25　W　was　achieved　with　an　input　power　of　4.7　W　by　a　5×5×2　mm　BBO　crystal,　corresponding　to　a　conversion　efficiency　of　26.6　%.　©　2018　Optics　InfoBase　Conference　Papers.　All　rights　reserved.
