LD-Pumped 355nm Ultraviolet Laser Of Continuous

In recent years,with technology development LD,LD-pumped solid-state laser with its small size,long life,high efficiency,good stability,become a research hotspotContinuous UV laser spectroscopy, laser medical, CD control, and so has an irreplaceable role. LD pumped solid-state ultraviolet laser available, and may replace the existing expensive and bulky gas lasers and excimer continuous UV light source, as the market main stream.This article from the LD-pumped 355nm ultraviolet laser produced a contnuous mechanism, this paper integrate theory with experiment, discussed the fundamental frequency and harmonic injection power density and temperature on the nonlinear crystal and furquency edfficiency.Take the side of the pump,by changing the cavity and the cavity length optimized for 532nm harmonic output,the use of intracavity frequency doubling and frequency cavity method,a good coupling of the 532nm and 1064nm fundamental frequency harmonic light,temperature control and frequency of the crystal case is 17℃,continuous access to 109mW of 355nm UV laser output.
