Paper Abstract

The Pulse Systems Inc. Model LP-140 is a commercial pulsed CO2 laser designed for marking and engraving. It is available with pulse energies in excess of 1 joule and repetition rates up to 7 Hz, thus making it a potential candidate for lidar applications. The authors document the characteristics of the LP-140 performance including power, temporal and spatial mode stability, chirp, and long term operational characteristics. The laser can be made to function as a coherent lidar only if modified to improve its inherent characteristics. This paper addresses work in progress on the following modifications and their effect on performance: gas flow, optical resonator configuration and discharge supply modifications.
