A 2.75‐GHz tunable CO2‐laser infrared source

摘要

By mixing a tunable millimeter‐wave signal with a fixed‐frequency CO2 laser beam in an electro‐optic crystal inside the laser cavity, a tunable 10‐μm signal of high spectral purity was obtained. The continuous tuning range achieved was 2.75 GHz, maximum output power was 0.8 mW.
