High efficiency, 100 mJ per pulse, Nd:YAG oscillator optimized for space-based earth and planetary remote sensing

• We build an efficient space flight-quality Q-switched laser for space-based uses.
• The pumping configuration employs thermal lensing to enhance performance.
• We operate 2 Billion shots, >110 mJ at 100 Hz PRF with no degradation.
• The unit is scalable and adaptable for planetary and Earth lidar missions.

We report on a newly solid state laser transmitter, designed and packaged for Earth and planetary space-based remote sensing applications for high efficiency, low part count, high pulse energy scalability/stability, and long life. Finally, we have completed a long term operational test which surpassed 2 Billion pulses with no measured decay in pulse energy.
