We demonstrate the high-power dual-wavelength laser output with disordered Nd:CNGG laser crystals. Continuous-wave output power of was obtained under the incident pump power of . In the passively Q-switched operation, the shortest pulse width, largest pulse energy, and highest peak power were achieved to be , , and , respectively, with crystals as the saturable absorbers. By spectral analysis, the output lasers were found to have dual wavelengths. We believed that the passively Q-switched dual-wavelength laser should be possible to be used as a source for the generation of terahertz radiation.
