CY0477 Neodymium-doped Gadolinium Orthovanadate (Nd:GdVO4)

Neodymium-doped Gadolinium Orthovanadate (Nd:GdVO4) Description

Neodymium-doped Gadolinium Orthovanadate (Nd:GdVO4) is a crystalline material used in the field of lasers and optics. It is a solid-state laser material that exhibits a high gain, high laser damage threshold, and a wide temperature range.

Nd:GdVO4 is a single crystal made by doping Gadolinium Orthovanadate (GdVO4) with neodymium ions (Nd3+). The neodymium ions replace some of the gadolinium ions in the crystal lattice structure, creating a neodymium-doped version. This doping process allows the crystal to possess specific optical and laser properties.

Nd:GdVO4 crystals are typically used as a laser gain medium, which means they amplify light signals by stimulated emission. When the crystal is excited with a pump source, such as a diode laser, neodymium ions absorb the energy and become excited. This excitation leads to the emission of laser light when the neodymium ions return to their ground state.

The crystal's properties, such as its high gain and low threshold, make it suitable for a wide range of laser applications, including medical lasers, industrial lasers, laser pointers, and scientific research. Nd:GdVO4 lasers can emit laser light in the near-infrared range, typically around 1064nm or 1342nm, depending on the doping concentration and the laser's design.
