Nd:GdVO4 (Neodymium doped gadolinium orthovanadate) is an excellent laser crystal for diode pumped lasers. Similar to the Nd:YVO4 crystals, Nd:GdVO4 also exhibits high gain. As well as this the crystal boasts low threshold, high absorption coefficients at pumping wavelengths. The following are the advantages of the Nd:GdVO4:
- Low lasing threshold and high slope efficiency
- High absorption coefficients can be achieved at pumping wavelengths
- Low dependency on pump wavelength
- Large stimulated emission cross section at laser wavelength
