Europe style for Rubidium Titanyle Phosphate - Yb:YAG Crystals – Dien

Yb:YAG is one of the most promising laser-active materials and more suitable for diode-pumping than the traditional Nd-doped systems. Compared with the commonly used Nd:YAG crsytal, Yb:YAG crystal has a much larger absorption bandwidth to reduce thermal management requirements for diode lasers, a longer upper-laser level lifetime, three to four times lower thermal loading per unit pump power. Yb:YAG crystal is expected to replace Nd:YAG crystal for high power diode-pumped lasers and other potential applications.
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.
