Sun Pumped Laser
Abstract
Results of an experimental program to determine the practicality of solar pumping a spaceborne optical communication laser are described. A feasibility model sun pumped Nd:YAG laser utilizing techniques compatible with space operation was built and successfully operated. Using a 24 inch diameter sun collecting mirror and an optical system which rejected the sun's IR radiation a power output of 1.6 watts was obtained from the laser. Without the IR filting (which also rejected some useful pump light) an output power of 1.2 watts was achieved with half of the telescope aperture area. Mode locked operation of the device at a rate of 500 MHz was also demonstrated. Based on sun pumpted laser performance achieved during the program it is projected that a laser output power of 1.6 watts can be obtained outside the earth's atmosphere with a 12 inch diameter mirror.
