摘要：

A　large-mode-area　double-cladding　Yb-doped　photonic　crystal　fiber　(PCF)　mode-locked　laser　based　on　semiconductor　saturable　absorber　mirror　(SESAM)　is　reported.　Without　any　pulse　compression　mechanism,　a　pulse　with　duration　of　3.3　ps　and　repetition　frequency　of　93.33　MHz　is　generated　in　a　ring　cavity　when　the　power　coupling　into　the　fiber　reaches　12.2　W.　The　central　wavelength　and　the　spectrum　bandwidth　are　1027　nm　and　1　nm,　respectively.　When　the　power　coupling　into　the　fiber　reaches　14　W,　a　maximam　output　power　of　150　mW　can　be　achieved.　The　laser　can　work　stably　for　2　h.　Q-switched　and　pulse　splitting　are　observed　and　analyzed.
