Large reflection coefficients during the four-wave mixing of CO2 laser emission in a fluid
Abstract
The four-wave mixing of 10-micron laser emission in carbon tetrachloride was implemented experimentally using both an ordinary and a feedback scheme. The gratings were recorded by a CW CO2 laser using the thermal inertial nonlinearity mechanism. In the ordinary scheme, the reading pulse length was about 0.2 microsecond, and the power reflection coefficient was about 2 x 10 to the 4th. In the feedback scheme, the lasing pulse length was about 0.2 microsecond, and the reflection coefficient was as high as 2 x 10 to the 5th.
