Abstract
This paper describes two versions of a mode-locked, internally frequency doubled Nd:YAG laser for use in a high data rate spaceborne optical communications system. The two versions are similar except for the method of optically pumping the rod. One is CW pumped with an alkali-metal vapor arc lamp operating at 250W input, while the other is pumped using sunlight collected by a 24-inch cassegrainian telescope. Mode-locking at a pulse repetition rate of 500 MHz and frequency doubling are accomplished using a single crystal of barium sodium niobate. Laser output powers in the TEM00 mode are 200mW and 400mW, respectively, for the lamp-pumped and sun-pumped versions with pulse widths of 300-400 ps (10% points). The mechanical and optical design of these lasers are discussed, and their pricipal performance characteristics are described.
