Abstract:

The effort has examined the isolation capabilities and overall operational efficiency of employing an acousto-optical frequency translator for the purposes of suppressing optical feedback generated instabilities in a laser MOPA chain. The operating principle is based on decoupling optical feedback from sustained laser oscillation by frequency translating the feedback such that it falls outside the gain bandwidths of any of the CO transition lines. Current progress has demonstrated successful optical feedback isolation, but, has experienced spurious acoustical and RF induced heating of the frequency translator which has limited its overall efficiency to approximately 10 percent.
