We demonstrate a strain compensated long lifetime semiconductor saturable absorber mirror (SESAM) with a high modulation depth for fiber lasers. The SESAM was measured to have a damage threshold of 9.5 mJ/cm2, a modulation depth of 11.5%, a saturation fluence of 39.3 μJ/cm2, and an inversed saturable absorption coefficient of 630 mJ/cm2. The SESAM has been applied to a linear cavity mode-locked Yb-doped fiber laser, which has been working for more than a year without damage of the SESAM.
