OPTICALLY PUMPED SEMICONDUCTOR LASER DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an optically pumped semiconductor laser device which can be manufactured as easily as technically possible.

SOLUTION: This optically pumped semiconductor laser device is equipped with a vertical emission portion 2 and at least one pump laser 5 for optically pumping the vertical emission portion. In the monolithically integrated semiconductor laser device, the pump laser has a radiant emission region 6 at a first temperature T1while the vertical emission portion has a radiant emission region 3 at a second temperature T2, which is higher than the temperature T1, during operation.
