Abstract

Saturated absorption at wavelength 3.39 Ɓm was observed with a CH₄ cell placed outside a laser resonator, with the aid of an optical amplifier tube through which a laser beam of 25 ƁW/mm² was amplified to 500 ƁW/mm². The observation of amplification and saturation of the optical amplifier was compared with theoretical predictions, and good agreement was obtained. The observed broadening rate of the CH₄ saturated absorption was (24.4±3.3) kHz/m Torr, and the geometrical broadening was (148ŷ18) kHz/mrad.
