Abstract
A housing for an optically pumped semiconductor (OPS) laser resonator is terminated at one end thereof by an OPS-chip. The laser resonator is assembled on a platform with the OPS-chip at one end of the platform. The platform is fixedly attached to a baseplate at the OPS-chip end of the platform. The remainder of the platform extends over the baseplate with a gap between the platform and the baseplate. A pump-laser is mounted directly on the baseplate and delivers pump radiation to the OPS-chip.
Claims7
Laser apparatus, comprising:
- a cantilever platform having first and second opposite ends;
- a baseplate having first and second opposite surfaces;
- an optically pumped semiconductor (OPS) laser-resonator including an OPS-chip, the OPS laser-resonator assembled on the cantilever platform with the OPS-chip bonded to a heat-sink attached to the first end of the cantilever platform;
- wherein the first end of the cantilever platform is supported on the baseplate, and a remaining portion of cantilever platform including the second end thereof extends over the baseplate with a gap between the remaining portion of the cantilever platform and the baseplate;
- and
- wherein a pump-radiation source is mounted on the first surface of the baseplate and arranged to deliver optical pump radiation to the OPS-chip for energizing the OPS laser-resonator.
