Performance and Aging of High Power 2-D Laser Diode Array

reportActive / Technical Report | Accession Number: ADA248821 | Open PDF

Abstract:

The effects of shot life on the output power, spectrum, near field, and far field patterns of a high power laser diode array have been measured and are reported, along with a description of the apparatus used to perform the measurements. The array operated for a total of 5.9 X 107 shots at a power output equivalent to 1 kWcM2. A 23 degradation in output power was observed, accompanied by a 3-nm red shift of the emission maximum. The effects of the measured drop in performance are particularly relevant to the application of these devices for pumping solid state lasers.
