Nd:YAG
Tianle Photonics manunfactures Nd：YAG for use in industrial,medical and scientific applications.The Nd:YAG continues as the best of the rare earth garnet materials that are characterized by four-level laser operation which permits low threshold pulse and cw operation.
Advantages of Nd:YAG lnclude:
l High gain
l Low threshold
l High efficiency
l Low loss at 1.06μm
l Good thermal conductivity and thermal shock characteristics
l Mechanical strength
l High optical quality
l Material characteristics that allow for various modes of operation (CW,pulsed,Q-switched,mode locked,and cavity dumped)
Tianle Photonics produces a wide variety of finished laser product,as well as supplying Nd:YAG material.Our general Nd:YAG production capabilities include:
l Slab-Custom Geometries
l Rod sizes from 1mm to 50mm in diameter and from 0.3mm to 220mm in length
l Nd dopant concentrations beween 0.1 and 2.5%
l Polished and AR coated barrels
l MIL-C-675C adhesion,abrasion and humidity resistance
l Damage threshold of over 750MW/cm2
l A wide variety of anti-reflection,partial reflector,high reflector and dichroic coatings
l Prewmium grade Nd:YAG,with lower wavefront distortion,is available upon request
