Passively Q-switched dual-wavelength laser output of LD-end-pumped ceramic Nd:YAG laser.
We reported a dual-wavelength laser with a ceramic Nd:YAG as laser material and Cr:YAG as frequency selector and saturable absorber. Continuous-wave output power was achieved to be as high as 6.19 W at 1052 nm. With Cr:YAG, the laser has dual-wavelength at 1052 and 1064 nm. The shortest pulse width, maximum pulse energy and highest peak power were 4.8 ns, 103.2 microJ, and 21.5 kW. This pulsed laser is possible to be used as a new source to generate terahertz radiation.
