AR Coated Nd:YVO4 Laser Crystals For DPSS Laser Product Description
With its exceptionally high stimulated emission cross-section, broad pump absorption bandwidth, and inherent birefringence, Nd:YVO₄ enables low-threshold, high-efficiency fundamental laser output in compact end-pumped configurations. It is the preferred gain medium for generating 1064 nm and 1342 nm near-infrared laser radiation, as well as intracavity frequency-doubled 532 nm green and 473 nm blue light. Asin Optics custom-manufactures 532 nm and 1064 nm Nd:YVO₄ laser crystals for diode-pumped solid-state (DPSS) lasers; these crystals are also utilized in laser micromachining, industrial marking, medical aesthetic lasers, and scientific research. We offer customization of doping concentrations to meet specific customer requirements.
AR Coated Nd:YVO4 Laser Crystals For DPSS Laser Key Features
- Nd:YVO4 laser crystals feature exceptionally high gain and efficiency, as well as a large stimulated emission cross-section at 1064 nm, making them ideal for micro-lasers.
- They possess a broad pump absorption band—specifically a strong, wide absorption peak at 808 nm—which minimizes the impact of pump wavelength drift on output stability.
- With an extremely low lasing threshold, Nd:YVO4 crystals are suitable for applications such as LD end-pumped microchip lasers and single-frequency seed sources.
They are exceptionally well-suited for high-frequency pulsed output, including Q-switched, picosecond, and nanosecond operations.

AR Coated Nd:YVO4 Laser Crystals Applications
Solid-State Laser Marking
Compared to Nd:YAG crystals, Nd:YVO4 possesses a larger stimulated emission cross-section and a broader absorption band at 808 nm. It absorbs pump energy more efficiently and achieves lasing at a lower threshold, making it ideal for high-efficiency pumping.
Medical Aesthetic Skin Treatment Equipment
Medical aesthetic equipment requires specific wavelengths to target pigmentation and achieve deep skin penetration. Nd:YVO4 offers exceptionally high pump conversion efficiency and supports intracavity frequency doubling with other nonlinear crystals, ensuring stable single-pulse energy.
Scientific Research and Micromachining
Precision cutting, drilling, and material micro-processing require short laser interaction times and high repetition rates. Nd:YVO4 laser crystals serve as the core gain medium; when used in resonators with acousto-optic or electro-optic Q-switches, they generate ultra-short pulses—ranging from nanoseconds to picoseconds—capable of vaporizing material while producing smooth edges.
