Abstract

We have constructed a single longitudinal mode XeCl laser using microwave discharge waveguide laser technology. The pulse duration, repetition rate, and simplicity of construction associated with waveguide excimer lasers lend this system unique capabilities and a broad utility for interfacing with other excimer devices. The coherence length of the laser emission has been found to be ~6 m with a corresponding bandwidth of <22 MHz that is near the transform limit. The laser has been used to demonstrate pulsed UV Doppler velocity measurement in a simple homodyne configuration.
