Laser Components is distributing Nd:GdVO4 crystals without a laser source. It is an excellent laser crystal for diode-pumped lasers, exhibiting a high gain, low threshold and high absorption coefficients at pumping wavelengths. The Nd:YVO4 also has a very high thermal conductivity, and it is thought it will replace Nd:YVO4 in high power laser applications in the future. Other advantages include high slope efficiency, low dependency on the pump wavelength, large stimulated emission cross section at the laser wavelength and a clear aperture with 90 per cent central area.
