Improved Passive Mode-locked Semiconductor Disk Laser (SDL)

摘要

A passive mode locked synchronous laser and a corresponding method are described. The laser terminates in the first (3) and second (4) mirrors and is folded by the third (5) and fourth (6) mirrors. The third mirror comprises a reflector (14) mounted on a multilayer semiconductor gain medium (15) having at least one quantum well layer and the second mirror (4) comprises an intensity saturation mirror. The resonator is configured to provide a cross-sectional area of the in-cavity resonant field on the intensity saturating mirror that is greater than or equal to the cross-sectional area of the in-cavity resonant field on the multi-layer semiconductor gain medium. This configuration provides a more stable passive mode-locked laser compared to systems known in the art.(FIG.
