✦ Synopsis

Degradation analysis is a crucial issue for the improvement of high power laser diodes. Degradation occurs in three different modes: rapid, gradual and catastrophic. It can be located inside the cavity or at the facet mirrors. Each type of degradation presents its own signature and different crystal defects appear associated with them. The main physical mechanisms responsible for laser degradation are analysed showing the relation between the main degradation modes and the different materials properties of the laser structures.

Schottky diodes may be realized by various techniques, depending on application and processing technology. M/A-COM has recently developed an enhancement/depletion (E/D) pHEMT process, used primarily for control circuits around its mature RF circuitry. We report here a reliability study of two diodes

We have successfully fabricated a new type of ytterbium-doped yttrium gadolinium aluminum garnet (Yb:GdYAG) laser ceramic using the solid-state reactive sintering method under vacuum condition. Continuous wave (CW) laser operation of the 5.0 at.% Yb:GdYAG ceramic laser has achieved 4.27 W output pow
