Mode selection and frequency tuning by injection in pulsed TEA-CO2lasers

An analytical model is presented which describes certain characteristics of the injection locking of a pulsed TEA-CO
2
laser by means of tunable CW laser radiation. The requirements for SLM generation as the injection frequency is tuned away from line center are discussed. Results indicate the practical importance of the locking time, a parameter which depends on both the injected power and the detuning from the molecular line center frequency.
