Ytterbium Doped Yttrium Aluminum Garnet (Yb:YAG Crystal)

Yb:YAG (Ytterbium Doped YttriumAluminum Garne ) crystal is one of the most promisinglaser-active materials and more suitable for diode-pumping then thetraditionalNd doped systems. It can be pumped at 0.94um laser output. Compared with the commonly used Nd:YAGcrystal. Yb:YAG (Ytterbium Doped YttriumAluminum Garne ) crystal has a much larger absorption bandwidth to reducesthermal management requirements for diode lasers, a longer upper-statelifetime, three to four times lower thermal loading per unit pump power. Yb:YAG (Ytterbium Doped YttriumAluminum Garne ) crystal is expected to replaceNd:YAG crystal for high power diode-pumped lasers and other potentialapplications. Yb:YAG shows great promise as a high power laser material. Several applications are being developed in the field of industrial lasers, such as metal cutting and welding. With high quality Yb:YAG now available, additional fields and applications are being explored. Coupletech provide the Advantages of Yb:YAG Crystal as below: Very low fractional heating less than 11%; Very high slope efficiency; Broad absorption bands, about 8nm@940nm;No exc ited-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: With a wide pump band and excellent emission cross-section Yb:YAG is an ideal crystal.
