We report on the fabrication of planar waveguide in Nd:YVO(4) crystal by using swift Ar(8+) ion irradiation. At room temperature continuous wave (cw) laser oscillation at wavelength of ~1067 nm has been realized through the optical pump at 808 nm with a low threshold of 9.3 mW. The slope efficiency of the waveguide laser system is of 8.5%. The optical-to-optical conversion efficiency is 6.6%.
我们报道了利用快氩离子（Ar⁸⁺）辐照在钕钇钒酸盐（Nd:YVO₄）晶体中制备平面波导的方法。在室温下，通过808 nm的光泵浦实现了波长约为1067 nm的连续波（cw）激光振荡，阈值低至9.3 mW。波导激光系统的斜率效率为8.5%，光光转换效率为6.6%。
