CY0477 Neodymium‐doped gadolinium orthovanadate (Nd:GdVO4)

Description of Neodymium-doped Gadolinium Orthovanadate (Nd:GdVO4)

Neodymium-doped Gadolinium Orthovanadate (Nd:GdVO4) is a crystalline material used in laser and optical applications. It is a solid-state laser material that exhibits high gain, a high laser damage threshold and effective operation over a wide temperature range.

Nd:GdVO4 is a single crystal produced by doping gadolinium orthovanadate (GdVO4) with neodymium ions (Nd3+). The neodymium ions replace a portion of the gadolinium ions in the crystal lattice, thereby creating a doped variant. This doping process imparts specific optical and laser characteristics to the crystal.

Nd:GdVO4 crystals are typically employed as the gain medium in lasers. When excited by a pump source, for example a diode laser, the neodymium ions absorb energy and become excited. The ions subsequently emit laser light as they return to their ground state.

The crystal’s properties, such as high gain and a low excitation threshold, make it suitable for various laser applications. These include medical lasers, industrial lasers, laser pointers and scientific research. Nd:GdVO4 lasers can emit near-infrared light, typically at approximately 1064 nm or 1342 nm, depending on the doping concentration and laser design.
