Abstract

The LCT/LOWKATER transmitter is a compact, medium power, repetitively pulsed, UV- preionized discharge, CO₂ laser currently producing a pulse 'chirped-tone' waveform intended for ground, airborne, or space-based ladar fire-control applications. Straightforward modifications can extend its applicability to higher resolution ladar ranging and imaging, generation of additional wavelengths via CO₂ isotopic selection and non-linear processes, and chemical detection and identification. For example, addition of an AO modulator will produce a coherent, pulse-burst waveform suitable for precision ladar ranging and imaging and efficient frequency multiplication into wavelength regions having good atmospheric transmission. Further addition of a rapidly tunable grating will yield a wavelength agile transmitter suited for chemical detection and identification. This device represents a versatile source of coherent radiation suitable for diverse applications sharing a common need for waveform fidelity from a compact transportable device.
