Passive Q-switching performance of intracavity frequency-doubled red laser with mixed Nd:GdxY1−xVO4 crystals

► The value of the passive losses is close for all Nd:GdxY1−xVO4 crystals. ► Nd:Gd0.63Y0.37VO4 possesses the lowest thermal conductivity. ► The largest pulse energy and peak power are achieved for Nd:Gd0.63Y0.37VO4. ► Nd:Gd0.63Y0.37VO4 could be the best for obtaining red Q-switched laser emission.
