Solid State Lasers XXVII: Technology and Devices(2018)
摘要
The high average power from pulsed good quality mode laser emitting at fundamental wavelength of 1066.3 nm is needed for obtaining of high-fidelity pulsed radiation with wavelength centered at 589.15 nm for spaceborne Na Doppler resonance fluorescence LIDAR. The conversion of radiation from 1066.3 nm to 589.15 nm can be achieved through one stage of Raman lasing and subsequent frequency doubling using qualified nonlinear crystals. Although efficient scaling of average power at 1064 nm using a-cut Nd:YVO4 to multiple of 10W was demonstrated for more than a decade ago, the efficient demonstration of 1066 nm power scaling from single Watt level to 10W level of average power is yet to be done. Multiple publications with a-cut Nd:YVO4 laser host with fundamental emission wavelength at 1064 nm showed good conversion efficiencies to both 1176 nm and to 588 nm using intracavity Raman lasing …
