Asin Optics customs and manufactures Nd:YAG crystal rod and Slabs For medical laser and high power LIDT applications in China. They are suitable for various operating modes: including continuous-wave, pulsed, Q-switched, and mode-locked operations, and are frequently utilized in near infared and far infrared solid-state lasers, as well as in second- and third-harmonic generation applications.
ND: YAG Crystals Rods and Slabs For High LIDT Product Discription
High-laser-damage-threshold (LIDT) Nd:YAG crystal rods and plates are core components of laser systems. Asin Optics is a manufacturer of laser crystals in China. By utilizing ultra-pure crystal raw materials, controlled crystal growth, uniform doping, and advanced coating technologies, we are able to provide high-quality Nd:YAG crystal rods and plates for nanosecond, picosecond pulses, and other high-power laser applications.
We support <111> and <100> crystal orientations, as well as a variety of standard and custom doping concentrations. In addition to offering high-LIDT coating services tailored to specific wavelengths and pulse widths, we can perform concentration doping, custom shaping, and processing of composite crystal bonding according to customer requirements.
Our Key Advantage Of ND: YAG Crystals Rods and Slabs
- We can provide ultra-high laser damage threshold coatings for crystals in wavelengths of 532nm, 355nm, 808nm, and 1064nm.
- We can achieve Nd doping concentrations from undoped to 2.5 at%, with highly doped Nd crystals being particularly suitable for microchip lasers, enabling higher energy output.
- Each crystal undergoes laser damage testing at specified wavelengths (1064 nm, 532 nm, 355 nm) before shipment, covering both 1-on-1 and S-on-1 specifications to ensure high batch-to-batch consistency.
Custom Capability Of Nd:YAG crystal Rod and Slabs
Nd:YAG Crystal Applications
Medical Aesthetics: Replacement Nd:YAG Rods for Q-switched Tattoos and Hair Removal Lasers.
Medical aesthetic lasers rely on high peak power 1064nm and frequency-doubled 532nm pulses. Their core gain medium—the Nd:YAG crystal rod—gradually develops color centers and subsurface microcracks after prolonged exposure to ultraviolet radiation and high-energy impacts, leading to decreased laser output energy and beam quality degradation. Our specially optimized high-LIDT medical laser replacement Nd:YAG rod perfectly matches the cavity design of mainstream Q-switched laser handpieces and hair removal devices on the market, thereby reducing the crystal rod replacement cycle and minimizing equipment downtime.
Industrial Processing: High-power Nd:YAG Slabs for Precision Welding, Marking, and Cutting Machines.
Traditional cylindrical high-power Nd:YAG rods suffer from severe thermal lensing and thermal birefringence under high pump power, limiting beam quality. We can provide Brewster corner facets, welded facets, or parallel facet strips coated with high LIDT films according to equipment manufacturers’ requirements, offering higher levels of doping uniformity and stability, translating beam quality into smaller focused spots and smoother cut facets.
Scientific Research: Custom-doped, Large-aperture Crystal Components for DPSS Systems.
High-energy-density physics, ultrashort pulse chirped pulse amplification (CPA), optical parametric chirped pulse amplification (OPCPA), and high-performance Ti:Sapphire pump sources require extremely low absorption loss, customized Nd:YAG doping concentrations, apertures up to tens of millimeters, and specific pulse widths. We work directly with research teams to provide custom-doped, large-aperture Nd:YAG crystal components for DPSS systems. Based on experimental design, customized Nd³⁺ doping concentration schemes, special crystal orientations, and large-diameter rod or strip geometries can overcome power and energy scaling bottlenecks, achieving shorter pulses and higher focal spot intensity.
