Performance of a sealed-off CO2-isotope laser amplifier for high resolution optical radar/lidar applications

The essential features and performance characteristics of a narrowband isotopic CO2 laser amplifier system are described. Sealed-off operation with over 30 dB net power gain, negligible frequency chirp and up to 70 microsec pulse duration, 300 mJ pulse energy, and 10 Hz pulse repetition rate have been achieved.
