摘要：

We　report　a　linear-cavity　mode-locked　Yb-doped　fiber　laser　using　self-made　semiconductor　saturable　absorber　mirrors　(SESAMs).　The　SESAMs　are　grown　by　means　of　metalorganic　chemical　vapor　deposition,　with　a　design　of　high　modulation　depth　using　strain-compensated　multiple　quantum　wells.　We　choose　two　kinds　of　self-made　SESAMs　with　different　periods　of　top　reflector　in　the　linear　cavity,　and　they　can　both　be　applied　to　stable　mode-locking　operation　without　damage.　The　output　characteristics　of　the　mode-locked　oscillator　indicate　that　SESAMs　with　high　modulation　depth　are　beneficial　for　mode-locked　fiber　lasers　and　the　modulation　depth　can　limit　the　pulse　width　of　the　output　pulses.　©　2021　Astro　Ltd　Printed　in　the　UK
