Nd:YVO4 Laser Rod Properties


                      

  








Neodymium:Yttrium Orthovanadate (Nd:YVO4) is one of the most efficient lasing media currently available. Nd:YVO4 lases at three wavelengths - 914nm, 1064nm and 1342nm.With a pumping wavelength of 808nm Nd:YVO4 is very well suited to diode-pumping.
