摘要：

In　this　research　work,　we　demonstrated　a　fiber-solid　state　hybrid　chirped　pulse　amplification　(CPA)　laser　system　with　high　pulse　energy　and　good　beam　quality　based　on　homemade　Yb:YAG　single-crystal-fiber　(SCF)　gain　module.　An　all-fiber　front　end　could　output　an　average　power　of　5　W　at　a　reoetition　of　500　kHz.　For　the　first-stage　SCF　amplifier,　we　utilized　high-brightness　laser-diode　(LD)　to　obtain　an　average　power　34.5　W.　For　the　second-stage　SCF　amplifier,　we　also　utilized　high-brightness　LD　to　obtain　an　average　power　71　W.　The　M2xM2y　were　1.26　and　1.25,　respectively.　Finally,　we　obtained　the　ultrafast　laser　output　with　an　average　power　of　51　W,　a　pulse　energy　of　102　μJ　and　a　pulse　duration　of　573　fs　after　pulse　compression.　©　COPYRIGHT　SPIE.
