摘要

We demonstrate a strain compensated long lifetime SESAM with a high modulation depth for fiber lasers. The SESAM was measured to have a damage threshold of 9.5 mJ/cm<sup>2</sup>, a modulation depth of 11.5%, a saturation fluence of 39.3 µJ/cm<sup>2</sup>, and an inversed saturable absorption coefficient of 630 mJ/cm<sup>2</sup>. The SESAM has been applied to a linear cavity mode-locked Yb:fiber laser, which has been working for more than a year without damage of the SESAM.
