Product description

 

Changhui-EO accept all OEM orders, send us the drawing, sample or idea are ok.

Nd:YAG crystal is the most widely used solid-state laser material today. It has been used in the 'micro/mini' 'DPSS' (Diode Pumped Solid State' laser system to get high quality Red, Green or Blue laser output in which the blue laser of Nd:YAG crystal has higher efficiency and more easy to realizes than Nd:YVO4 crystal blue laser. Nd:YAG crystal was also widely used in the military, scientific, medical and industrial laser systems, high performance scientific laser systems, laser therapy, cosmetology systems, laser marking, laser drilling and other laser material processing systems. Especially, Nd:YAG crystal is the best laser material for the high power, high energy, and Q-switched pulse laser systems. The very wide applications of Nd:YAG crystal in various laser system is because its outstanding performance in physics and mechanics.

Advantages of Nd:YAG crystals

  • High gain
  • Low threshold
  • High efficiency
  • Low loss
  • Suitable for different modes of operation (cw, pulsed , Q-switched,
  • mode locked, doubling of frequency )
  • Suitable for high-average power lasers
  • Good thermal conductivity and thermal shock characteristics
  • Large mechanical strength
  • High optical quality
