Paper Abstract

Two Lambda Physik EMG2O3MSC excimer lasers were modified to pump a single dye oscillator cell providing a 500 Hz source for a Tuneable Airborne LIDAR (LIght Detection And Ranging) Transmitter. This modification to the standard Lambda Physik dye oscillator/amplifier design produced a significant weight reduction along with simplicity in alignment, both key aspects in an airplane environment. Previous modification included conversion to 400 Hz power, which increased beam divergence, but also increased the pulse energy. The Pulsewidth remained the same and the polarization had a preferred horizontal direction. We used Coumarin 102 dye as the lasing medium, providing tuneability from 470-510 nm with energy efficiences of 20% at the peak wavelength of 480 nm, which corresponds to a photon conversion efficiency of 31%.
