High-Power Laser Ablation V.
In this paper, we summarize the performance of a diamond cooled diode pumped solid state (DPSS) Nd:YAG laser developed by Textron Systems Corporation (TCS). Over 50% intrinsic extraction efficiency at 50-Watts average power, equivalent to volumetric

The pulse separation and associated range ambiguity of a CO 2 laser radar using a pulse burst waveform consisting of 1.3 ns mode-locked pulses spaced 40 ns apart was successfully doubled to 80 ns and 12 m respectively by suppressing every alternate p

We have demonstrated a 15 dB lidar receiver detection sensitivity improvement by employing an Er3+-doped fiber preamplifier as the input to an InGaAs P-I-N photodiode. This eye-safe, 1550 nm detection system can significantly improve lidar system per

Symmetrical edge and face cooling geometries have been evaluated as a thermal control technique for a high power acousto-optic modulator employed as an intracavity mode locker inside a pulsed TE, 0.5 atm, mode-locked CO2 laser oscillator with a 0.5 -

A large-aperture, high-Q, germanium standing-wave AO modulator for mode locking a pulsed high-energy CO2 laser is described. By operating it in the Raman-Nath regime, optical absorption-induced thermal lensing effects are minimized. Due to a smaller

Coherent Laser Radar: Technology and Applications.
A conceptual design study of the laser transmitter was completed during Phase A of the NASA's LAWS instrument development program. The proposed LAWS instrument is a space-based doppler lidar wind profiler consisting of a pulsed, frequency-stable lase
