Third harmonic generation in ethylene

V. N. Varakin, V. M. Gordienko


Abstract: The first study was made of resonant generation of the third harmonic of a CO₂ laser in ethylene. The conversion efficiency reached a maximum at 951 cm^–1 on the high-frequency side of the ν₇ absorption line. Measurements were made of the third-harmonic signal as a function of the pressure and laser radiation power.
