ABSTRACT
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 5.28 W at 1052 nm was achieved. With Cr:YAG, the laser has a dual-wavelength output at 1052 and 1064 nm. The maximum average output power, pulse repetition rate, and pulse energy are 3.75 W, 41.2 kHz, and 90.1 μJ, respectively. We also found that the intensity ratio of the two oscillating modes can be tuned by adjusting the pump power.
