Fast linear detection system for TE CO2 lasers

Abstract
A preliminary study of up‐conversion as an approach to high‐speed detection of 10.6‐μm laser radiation is reported. Using synchronized Nd : YAG and TEA CO2 lasers, conversion to 0.96‐μm radiation in proustite has permitted the detection of mode‐locked TEA laser pulses with an overall system bandwidth of 900 MHz.
