Description

YAG crystal is the most commonly found solid-state laser material adopted by R&D, industrial, medical, and military customers. Its main advantages are: low lasing threshold, high gain, high efficiency, low loss at 1064 nm, as well as high optical quality, good thermal conductivity and thermal shock characteristics and mechanical strength properties, which make Nd:YAG as the most suitable and commercial laser material for CW, pulsed, mode locked lasing Nd:YAG crystals are also widely used in all types of solid-state laser systems-frequency-doubled continuous wave, high-energy Q switched, and cavity dumped modes of operation.

we are able to stably supply a wide variety of Nd:YAG rods with high optical homogeneity, consistent performance, high processing accuracy for R&D and OEM requirements.
Our general Nd:YAG production capabilities include:
•Rod sizes from 3mm to 14mm in diameter and from 1mm to 160mm in length
• Nd dopand concentration between 0.6 at～1.2 at%
• Anti-reflection Coating:R<0.2%@1064nm
• High transmission Coating: T>95% @ 808nm
High reflection Coating: R>99.8 @ 1064nm
