1.3-μm Mode-Locked Disk Laser With Wafer Fused Gain and SESAM Structures

Elyahou Kapon, Alexei Sirbu, Alexandru Mereuta, Andrei Caliman

We report 1.3-mu m mode-locked optically pumped semiconductor disk laser (SDL) made by wafer fusion. The gain medium and the saturable absorber, both based on an InP material system, were integrated with AlGaAs-GaAs distributed Bragg reflectors by localize ...

3 W of 650 nm red emission by frequency doubling of wafer-fused semiconductor disk laser

Elyahou Kapon, Alexei Sirbu, Alexandru Mereuta

3 W at genuine red wavelength of 650 nm has been achieved from a semiconductor disk laser by frequency doubling. An InP based active medium was fused with a GaAs/AlGaAs distributed Bragg reflector resulting in an integrated monolithic gain mirror. 6.6 W of ...
