Product overview

Neodymium doped Yttrium Aluminum Garnet (Nd:YAG) crystal is the most commonly laser material for CW laser, Pulsed laser, Mode Locked Laser and also widely used in all types of solid-state laser system, frequency-doubled continuous wave, high-energy Q switched, and cavity dumped modes of operation. We can offer Nd, Er, Cr, Tm, Yb, Ho and no doped YAG crystals.


Scitlion is able to offer
Nd dopand concentration from 0.6% to 1.2% (atm%)
Cr dopand concentration from 0.5% to 3% (m
ol%)
Yb dopand concentration from 5% to 15% (atm%)
Rod diameter from 2mm to 16.5mm
Length from 1mm to 180mm
