Product Description
Crystro Nd:Y3Al5O12 Laser Crystal For Solid State Laser As Lasing Medium
Birefringent Crystals Undoped Yttrium Vanadate YVO4 Crystal
1.Introduction:
Nd:YAG absorbs mostly in the bands between 730–760 nm and 790–820 nm. At low current densities krypton flashlamps have higher output in those bands than do the more common xenon lamps, which produce more light at around 900 nm. The former are therefore more efficient for pumping Nd:YAG lasers.
