Product overview

Nd:GdVO₄ crystals can be specified with different Nd³⁺ dopant concentrations, crystal orientations, dimensions, end-face geometries, surface quality requirements, transmitted wavefront tolerances, and optical coatings.

Nd:GdVO₄ (neodymium-doped gadolinium orthovanadate) is a laser gain crystal used in diode-pumped solid-state (DPSS) laser systems. Its principal laser emission is near 1063 nm, with strong pump absorption around 808 nm.

As a tetragonal vanadate crystal, Nd:GdVO₄ provides linearly polarized laser emission, typically parallel to the crystallographic c-axis. It combines strong pump absorption with favorable thermal properties for compact diode-pumped laser designs.

Nd:GdVO₄ can also support laser transitions in the 1.34 µm region and can be used in frequency-converted solid-state laser systems with suitable nonlinear crystals and resonator configurations.

Key advantages

  • Strong pump absorption near 808 nm
  • Higher thermal conductivity than Nd:YVO₄
  • Linearly polarized emission (E ∥ c-axis)
  • Laser transitions near 1063 and 1340 nm

Representative examples

  1. 3 × 3 × 12 mm, 0.3 at.% doping, optically polished and AR-coated at 800 nm and 1342 nm
  2. 4 × 4 × 7 mm, 0.3 at.% doping, optically polished and AR-coated at 800 nm and 1342 nm

Typical applications

  • Compact diode-pumped solid-state laser systems
  • Laser sources operating around 1063 nm
  • DPSS laser systems with demanding thermal-management requirements
  • Laser sources operating near 1.34 µm
  • Frequency-converted solid-state laser systems
  • Scientific and laboratory laser systems
  • Medical and ophthalmic laser systems
