Abstract :
A 2-dimensional waveguide model was successfully implemented to maximize the kink-free power from 980 nm pump lasers. Additionally, we show that high quality single crystal mirrors can be deposited epitaxially by MBE to eliminate COMD as a failure mode in these devices. Using state of the art manufacturing and packaging capabilities, the high power chip has been incorporated into the design of a high power wavelength stabilized 980 nm pump laser module. A typical curve showing fiber coupled power as a function of drive current for this family of laser modules is shown.
