Ytterbium Doped YAG Crystal Product Attributes
Ytterbium Doped Yttrium Aluminum Garnet (Yb:YAG Crystal) is one of the most promising laser-active materials and more suitable for diode-pumping than the traditional Nd- doped systems. It can be pumped at 0.94um laser, and it is output 1030nm Laser Crystal. Compared with the commonly used Nd:YAG crystal. Yb:YAG (Ytterbium Doped Yttrium Aluminum Garne ) crystal has a much larger absorption bandwidth to reduce thermal management requirements for diode lasers, a longer upper-state level lifetime, three to four times lower thermal loading per unit pump power. Yb:YAG ( Ytterbium Doped Yttrium Aluminum Garne Crystal) shows great promise as a high power laser material and several applications are being developed in the field of industrial lasers, such as metal cutting and welding. Coupletech provide the Advantages of Yb:YAG Crystal with very low fractional heating less than 11%; Very high slope efficiency; Broad absorption bands, about 8nm@940nm; No excited-state absorption or up-conversion; Conveniently pumped by reliable InGaAs diodes at 940nm(or 970nm); High thermal conductivity and large mechanical strength; High optical quality. The Applications of Yb:YAG are with a wide pump band and excellent emission cross-section Yb:YAG is an ideal crystal for diode pumping; High Output Power; Laser Material for Diode Pumping; Materials Processing, Welding and Cutting. The specifications of Yb:YAG are as below: wavelength is 1030nm; chemical formula is Y3Al5O12:Yb; orientation within 5 degree; parallelism is ≤ 10"; perpendicularity is ≤ 5′; flatness is 0.1 wave maxismum; surface quality at 5X is 20-10. You can customise the Yb:YAG crystal to your needs. If you do not find suitable specifications for your application please contact us for custom solution.

Nd:YVO4 is one of the most promising commercially available diode pumped solid state laser materials. It has high laser induced damage threshold and good mechanical in addition to optical properties. Its large stimulated emission cross-section and high absorption of pump laser make it a right crystal for pocket laser. Nd: YVO4 can produce IR green and blue laser by using minor different set-up. A broad absorption band centered at 808nm and favorable mechanical properties make Nd:YVO4 well suited for compact, efficient, high power diode-pumped lasers. Natural birefringence gives rise to a highly polarized output at 1064.3 and 1342nm.
