Vi. Kovalev et Mb. Suvorov, REFLECTION EFFICIENCY AND RESPONSE RELAXA TION-TIME IN DEGENERATE 4-WAVE-MIXING IN THE ACTIVE MEDIA OF TEA CO2-LASERS, Kvantovaa elektronika, 23(1), 1996, pp. 12-16
An experimental investigation was made of the reflection by a nonlinea
rity from gain saturation in the active medium of a TEA CO2 laser unde
r degenerate four-wave mixing conditions. A new mechanism of relaxatio
n of the response to such a nonlinearity was identified and processes
with submicrosecond and subnanosecond relaxation times were found in C
O2. The saturation intensities for these processes and the conditions
For achieving high reflection intensities as a result of such a mixing
were determined.
