The heartbeat length of the 2nd Stokes light was shortened to 5 ns as shown in Determine 7a, one-shot photograph from your oscilloscope, which is a common phenomenon in Raman laser [44] when the heartbeat duration in the pump laser was ten ns.
Cesium Lithium Borate (CsLiB6O10 or CLBO) is the simplest non-linear crystal which generates ultraviolet harmonics on the Nd:YAG essential laser wavelength. To be able to improve the harm threshold, reduced CLBO surface roughness, by extremely-precision machining, is required. Because the CLBO crystal has easy hydroscopic response and micro scratches in machining, ultra-specific machining with the CLBO crystal can be a challenging technical trouble.
The beam profile proven in Determine 7b shown a good beam top quality as among the list of deserves of Raman laser, which might be effective to produce a 193-nm DUV laser with a high quality beam.
