We report an efficient laser emission on the 1066 nm 4 F 3/2 to 4 I 11/2 transition in Nd:LuVO4 under the pump with diode laser at 888 nm. Continuous wave (CW) 11.2 W output power at 1066 nm is obtained under 18.3 W of incident pump power; the slope efficiency with respect to the incident pump power was 71.9%. Moreover, intracavity frequency doubling with LiB3O5 (LBO) nonlinear crystal yielded 4.2 W of green light at 533 nm. An optical-to-optical efficiency with respect to the incident pump power was 23.0%. 相似文献

We present for the first time a Nd:YVO4 laser emitting at 1064 nm intracavity pumped by a 916 nm diode-pumped Nd:LuVO4 laser. A 809 nm laser diode is used to pump the Nd:LuVO4 crystal emitting at 916 nm, a Nd:YVO4 laser crystal was pumped at 916 nm and lased at 1064 nm. Intracavity sum-frequency mixing at 916 and 1064 nm was then realized
in a LiB3O6 (LBO) crystal to reach the blue range. We obtained a continuous-wave output power of 216 mW at 492 nm under 19.6 W of incident
pump power at 809 nm. 相似文献

The efficient dual-wavelength oscillation at 1064 and 1342 nm in the passively Q-switched laser based on Nd:YVO4/V3+:YAG is successfully obtained, as demonstrated in this paper. A total average output power of 2.2 W is obtained with 1.3 W
for 1064 nm and 0.9 W for 1342 nm under the incident pump power of 7.7 W, corresponding to a total optical-optical conversion
efficiency of 28.2%. The pulse widths are 58 and 54 ns for 1064 and 1342 nm, respectively, with the repetition rate of 89
kHz. Moreover, a rate equation model considering the Gaussian spatial distributions of the intracavity photon density and
the initial population-inversion density is presented to characterize the dual-wavelength passive Q-switching operation. 相似文献
