Nd:YVO4 – The Superior Laser Crystal for Diode Pumping
Nd:YVO4 (Neodymium Doped Yttrium Orthovanadate) is recognized as the most efficient laser host crystal for diode pumping, especially for low to middle power applications. It surpasses Nd:YAG in terms of absorption and emission features, making it the preferred choice in various industries. With its exceptional performance, Nd:YVO4 has found its place in a wide range of applications, from material processing to medical diagnostics and laser printing.
Key Features and Benefits:
- High Absorption Efficiency: Nd:YVO4 has up to five times greater absorption efficiency around 808 nm compared to Nd:YAG, enabling efficient pumping with a broad bandwidth. This results in reduced dependency on pumping wavelength and a higher likelihood of achieving single-mode output.
- Enhanced Stimulated Emission Cross-Section: The stimulated emission cross-section at the lasing wavelength of 1064 nm is three times larger than that of Nd:YAG, providing higher output power and efficiency.
- Lower Lasing Threshold & Higher Slope Efficiency: Nd:YVO4 exhibits a lower lasing threshold and higher slope efficiency, ensuring optimal laser performance with reduced energy consumption.
- Uniaxial Crystal with Large Birefringence: As a uniaxial crystal, Nd:YVO4 has large birefringence, ensuring the emission is linearly polarized, which is essential for many precision applications.
- Compact & Versatile: Ideal for solid-state laser systems, Nd:YVO4 crystals can be used with nonlinear optical (NLO) crystals like LBO, BBO, or KTP to convert the output into green, blue, or even UV wavelengths, expanding its range of applications.
Applications:
- Laser Machining & Material Processing: High efficiency makes it ideal for precision cutting, welding, and engraving applications.
- Spectroscopy & Wafer Inspection: Provides consistent, high-quality output for scientific and industrial inspections.
