AlGaInAs intracavity selective absorber for an efficient high-power Nd:YAG laser operation at 1.44 microm.
We develop an AlGaInAs material as a promising intracavity selective absorber for an efficient high-power Nd:YAG laser at 1.44 microm. With the ISA to suppress operation at 1.06 microm, the output coupler at 1.44 microm can be straightforwardly designed and optimized. At a pump power of 16 W an output power of 2.5 W at 1.44 microm, with a slope efficiency of 23%, was achieved.
