A method has been developed for testing the stability of micro-optical bonds. A white light interferometer is used to measure the movement of micro-optical components after each of a series of Telcordia tests. The micro-optical components were subjected to accelerated high temperature soak, thermal cycling, thermal shock and 500 G mechanical shock. This method allows us to have a high level of confidence that our optical bonds will be sufficiently stable throughout the service life of our tunable laser product. Using accelerated testing techniques and not performing environmental tests that have been shown to induce minimal or no movement, we have found that 30 days is the time required to adequately evaluate the stability of a micro-optical bond design.
The design and performance of a large diode-pumped multi-stage Nd:YAG laser system for space and airborne applications will be described. The laser operates at a repetition rate of 40 Hz and produces an output either at 1.064 micron or 532 nm with an average power in the Q-switched mode of 30 W at the fundamental and 20 W at the second harmonic wavelength. The output beam is diffraction limited (TEM 00 mode) and can optionally also be operated in a single longitudinal mode. The output energy ranges from 1.25 Joule/pulse in the free lasing mode, 0.75 Joule in a 17 nsec Q-switched pulse, to 0.5 Joules/pulse at 532 nm. The overall electrical efficiency for the Q-switched second harmonic output is 4.
