Yb:YAG lasers have many advantages compared with diode-pumped rod-based Nd:YAG systems，such as superior beam quality, efficiency, and tunability. Yb:YAG is a quasi-three-level structure crystal with the low quantum of loss, thermal load, very low thermal permeability, easy to obtain high output, and can output a maximum of 100W at 1030nm，ensuring the output mode is TEM00.Thin-disc Yb:YAG lasers are aiming for the engraving and printing markets.
Gain medium - Nd YAG
Thin disk made of Yb：YAG. The crystal shape of the thin disk laser is a sheet type.The entire crystal of thin disk is bonded to the heat sink, so the cooling efficiency of the crystal is very high. Becasue the thickness of the crystal is very thin, only a part of the pump light is absorbed by the crystals every time while it passes through the laser crystals. In order to improve its pumping efficiency, a parabolic mirror is placed at the front of the semiconductor to produce output light with high power.
