Dual-wavelength neodymium-doped yttrium aluminum garnet laser with chromium-doped yttrium aluminum garnet as frequency selector
Haohai Yu, Huaijin Zhang, Zhengping Wang, Jiyang Wang, Yonggui Yu et al.
We report on a potential source for the generation of terahertz radiation using the well-known neodymium-doped yttrium aluminum garnet as the laser material, and chromium-doped yttrium aluminum garnet (Cr:YAG) as the frequency selector and saturable absorber. Continuous-wave output power as high as … [Appl. Phys. Lett. 94, 041126 (2009)] published Fri Jan 30, 2009.
