Abstract

Infrared upconversion is the only currently available diagnostic technique for 10-μm CO₂ laser pulses that provides both linearity and picosecond time-resolution capability. We report an investigation of the linearity for upconversion of nanosecond CO₂-laser pulses in proustite pumped by a Nd:YAG laser. This was examined over three orders of magnitude of infrared intensity, and peak pump quantum-conversion efficiencies of 30% were obtained.
