Self-starting mode-locked Cr(4+):YAG laser with a low-loss broadband semiconductor saturable-absorber mirror.
We report a self-starting mode-locked Cr(4+):YAG laser with a low-loss broadband metal reflector-based semiconductor saturable-absorber mirror. The minimum pulse width was 44 fs at a wavelength of 1520 nm.
