Laser properties of Yb:YGAG ceramic in comparison with crystalline Yb:YAG
Original language description
The progress in diode-pumped high average power short pulse lasers led to development of the concept of thin-disk lasers with its workhorse material Yb:YAG. The power scaling of thin-disk lasers via enlarging the pump spot on the active medium requires growing of large crystals, which is difficult and motivates the development of ceramic materials. Another way to deal with the thermal issues of high energy lasers is to cool the laser medium to cryogenic temperatures. However, for many materials, including Yb:YAG, this leads to a significant narrowing of absorption and emission bandwidth, impeding the generation of short pulses. The Yb-doped mixed garnet Y3Ga2Al3O12 (YGAG) emerges as a suitable candidate, as its spectroscopic properties are not so strongly affected by the decreasing temperature, as indicates Tab. 1. With this motivation we study the laser properties of Yb:YGAG ceramic as an alternative to the more prevalent crystalline media.
