Product Description

Nd:YAG crystals

Nd:YAG is the earliest and most famous laser host crystal. Since it combines great advantages in many basic properties, Nd:YAG is the ubiquitous presence for near-infrared solid-state lasers and their frequency-doubler, tripler, and higher order multiplier.

 

Advantages Of Nd:YAG

• High gain;

• Low threshold;

• High efficiency;

• Low loss at 1064nm;

• Good thermal conductivity and thermal shock characteristics;

• Mechanical strength;

• High optical quality;

• Material characteristics that allow for various modes of operation (CW, pulsed,Q-switched, mode locked).
