Nd: YVO4 laser crystal

 Bernard Azout

Key Features:

  • High absorption over a wide pumping wavelength bandwidth
  • Larger stimulated emission cross-section at the lasing wavelength of 1064nm
  • Lower lasing threshold and higher slope efficiency
  • As a uniaxial crystal with a large birefringence, the emission is only a linearly polarized


Nd: YVO4 has become popular host crystal for diode pumping among the current commercial laser crystals because of its high gain, low threshold and high absorption coefficients at pumping wavelengths, which result from the excellent fit of the neodymium dopant in the crystal lattice. This is mainly for Nd:YVO4’s absorption and emission features surpassing Nd:YAG Pumped by laser diodes. Nd:YVO4 crystal has been incorporated with high NLO coefficient crystals (LBO, BBO or KTP) to frequency-shift the output from the near infrared to green, blue, or even UV.
