Neodymium Doped Gadolinium Orthovanadate (Nd:GdVO4) is a high-performance laser host crystal optimized for diode-pumped solid-state lasers (DPSSLs). Its excellent physical and optical properties make it a preferred material for high-power applications. Nd:GdVO4 offers a larger stimulated emission cross-section and higher energy absorption efficiency than Nd:YVO4, with better thermal management capabilities.
This crystal is particularly suitable for applications requiring high power density and efficient energy conversion. Its superior thermal conductivity supports continuous-wave and pulsed laser operations, enabling compact laser designs with high output stability. The uniaxial birefringence of Nd:GdVO4 ensures linearly polarized emission, making it highly effective for frequency doubling and nonlinear processes.
Nd:GdVO4 crystals are widely used in industries such as material processing, medical instrumentation, spectroscopy, and scientific research.
Nd:GdVO4 crystals are versatile and widely used in high-performance laser systems. Some key examples include:
