Nd: YAG Crystal |
Description: |
Neodymium Doped Yttrium AIuminum Garnet (Nd: YAG) Crystal Nd: YAG crystal is the most widely used solid-state laser material today. Now, we are able to stably supply quantity of Nd: YAG rods with high optical homogeneity, consistent performance, high processing accuracy and on time delivery. 1.

Standard Products specification Dopant Concentration (atomic %): 0.9%~ 1.1% Orientation: <111> crystalline direction (±5o) Wavefront distortion:l/8 per inch, measured by a double-pass interferometer @ 633 nm Extinction Ratio: Rods with diameter from 3 mm to 6.35 mm and with length to 100 mm:>30dB Rods with diameter from 7 mm to 10 mm and with length to 100 mm:>28dB Dimension Tolerances Rods with diameter: ±0.025 mm (±0.001"), Length: ±0.5 mm (±0.02") Barrel Finish:50 80 micro-inch (RMS) , grooved rod barrel are also available Ends Finish: Surface Figure: <l/10 @ 633 nm Parallelism: < 10 arc seconds Surface quality:< 5 arc minutes Clear Aperture: > 10/5 Scratch / Dig per MIL-O-1380A chamfer:<0.1 mm @ 45° clear Aperture: extend over the entire faces to the chamfered edges Anti-Reflection Coating: Single layer MgF2 coating with high damage threshold for high power laser operation. Reflectivity R < 0.25% @ 1064 nm per surface. Damage threshold over 750 MW/cm2@ 1064nm, 10 ns and 10 HZ. High-Reflection Coating: Standard HR coating with R>99.8% @ 1064nm and R<5% @ 808nm can be performed in WTS. Other HR coatings, such as HR @ 1064/532 nm, HR @ 946nm, HR 1319 nm and other wavelengths are also available. Standard products in-stock: The standard Nd: YAG laser rod with dimension of f3x5 mm and f4x50 mm with AR or HR- coating for Diode Pumped Solid State Lasers (DPSS) are ready for immediate delivery. For more information about standard Nd: YAG rods please refer to page 62 of Diode Pumped Laser Optics Kits. Note:Higher grade or specific Nd: YAG rods or slabs are also available upon request.
