Single-frequency Q-switched Cr,Nd:YAG laser operating at 946-nm wavelength

Single-frequency Q-switched operation in 946-nm wavelength has been demonstrated by application of a monolithic Cr,Nd:YAG cavity. In this device, the Cr,Nd:YAG laser material performs the functions of light modulation, frequency stabilization, and polarization selection. The conditions for the single-frequency operation and maximum degree of polarization are discussed.
