Nd:yag laser crystal 1.Good anti-UV irradiation property 2.Good thermal stability 3.High optical quality
Introduction:
Nd:Ce:YAG is an excellent laser material used for no-water cooling and miniature laser systems. The Nd, Ce: YAG laser rod we produce has the characteristics of high efficiency, low threshold, anti-violet radiation for lasers operation. As a result - thermal distortion in Nd: Ce:YAG is appreciably less and the output laser energy is greater( 30%-50%) than that in Nd:YAG at the same pumping. It is the most ideal laser material for the air cooling lasers .It is suitable for different modes of operation ( pulsed , Q-switched, mode locked) and high-average power lasers. Advantages of Nd:Ce:YAG Include:Low thresholdVery high slope efficiency(20-40% more than Nd:YAG)Good anti-UV irradiation propertyGood thermal stabilityHigh optical quality We have a wide variety of finished laser product,as well as supplying Nd:Ce:YAG material.Our general Nd:Ce:YAG production capabilities include:Rod sizes from 2mm to 15mm in diameter and from 1mm to 115mm in lengthNd dopant concentrations beween 0.6 and 1.3%Polished and AR coated barrelsMIL-C-675C adhesion,abrasion and humidity resistanceA wide variety of anti-reflection,partial reflector,high reflector and dichroic coatingsPremium grade Nd:YAG,with lower wavefront distortion,is available upon request Typical finished part specifications and tolerances are listed below.
