Abstract:

THIS EFFORT WILL SHOW FEASIBILITY OF A COMPACT COHERENT SOLID-STATE LASER SOURCE RESULTING IN SIGNIFICANT ADVANTAGE OVER THE MASTER OSCILLATOR POWER AMPLIFIER (MOPA) CONFIGURATION, ESPECIALLY FOR SPACE-BASED OPERATION. THE PULSE-STRETCHED, SINGLE-LONGITUDINAL-MODE (SLM), SOLID-STATE SOURCE OPTIMIZES THE CURRENT LASER TECHNOLOGY FOR COMPACTNESS AND POWER EFFICIENCY, NECESSARY FEATURES OF A SPACE-BASED LIDAR. DOPPLER LIDAR WIND SENSORS REQUIRE HIGH ENERGY LASER PULSES FOR LONG RANGE. THE NEED FOR DOPPLER VELOCITY ACCURACY TYPICALLY REQUIRES COHERENT PULSES WHOSE DURATION IS GREATER THAN 1 MICROSECOND. CURRENT REALIZATION OF COHERENT LONG-PULSE OUTPUT FOR SOLID-STATE LASER SOURCES INVOLVES THE USE OF A HIGHLY STABLE, LOW ENERGY MASTER OSCILLATOR WHOSE OUTPUT IS THEN AMPLIFIED BY POWER AMPLIFICATION STAGES (MOPA). ALTHOUGH THIS TECHNIQUE IS EFFECTIVE, IT IS RELATIVELYLARGE IN SIZE AND ENERGY INEFFICIENT. WE PROPOSE TO DESIGN AN EFFICIENT LONG-PULSE SOLID-STATE LASER BY COMBINING THE BENEFITS OF INJECTION SEEDING AND PULSE STRETCHING. THIS EFFORT WOULD RESULT IN THE DESIGN OF AN EFFICIENT SLM SOLID-STATE LASER WITH PULSE DURATIONS UP TO SEVERAL MICROSECONDS AND FREQUENCY BANDWIDTHS OF LESS THAN 2 MHZ.
