Light beam frequency conversion method by cesium lithium borate crystals, involves passing through of light beam with input light power along optical path interspersing cesium lithium borate crystal with output light power

摘要

The method involves passing through of a light beam with an input light power along an optical path interspersing the cesium lithium borate (CLBO) crystal with an output light power for time for the receipt of a ray of light containing frequency-doubled wavelength portions by the CLBO crystal. The CLBO crystal before or during the passing through of light beam by the CLBO crystal is brought on a source temperature which is held steady for the initial time period. The output temperature is so selected that it lies between the two temperatures.
