Development of a Diode-Pumped Laser for Space-Based Communications

Abstract:

A high-power, single-frequency lasers based on a unique, modular, neodymium (Nd)
gain-element pumped by an array of semiconductor diode lasers will be developed.
This device would be capable of driving a compact, multi-Watt laser transmitter in
a space-based communication system. Output powers in excess of 10 W could be generated
by including multiple gain elements in a single laser resonator. The primary goals
of the Phase I effort are design and construction of a prototype gain module including
a 10-W, GaA1As, laser array and demonstration of a single-frequency, ND:YAG laser
built around the prototype module and capable of generating approximately 2W at 1064
nm.
Single-frequency, high-power, diode-pumped Nd lasers will find immediate application
as master oscillators, transmitters, and receivers for coherent LIDAR and communications
systems. With second harmonic generation, they will provide an all-solid state replacement
for air-cooled and small-frame argon-ion lasers.
