Yb:YAG Laser Crystals For High-Power Diode-Pumped Applications
-
High-Power Industrial Lasers
High-power continuous-wave industrial lasers require gain media with high thermal conductivity, low thermal lensing, and high conversion efficiency. Yb:YAG with high doping concentrations enables highly efficient absorption over an extremely short gain length. Furthermore, the broad absorption bands of Yb:YAG at 940 nm and 969 nm significantly reduce the requirements for pump diode wavelengths, making it highly suitable for industrial production line environments
-
Ultrafast Lasers
Ultrafast laser amplifiers require gain media with high energy storage capacity, broadband gain, and extremely low thermal distortion to maintain pulse widths in the picosecond and nanosecond ranges. In ultrafast systems, Yb:YAG primarily serves as the gain medium for regenerative amplifiers or traveling-wave amplifiers, enabling high-power ultrafast output with hundreds of watts of average power. It is particularly suitable for applications such as cutting high-hardness transparent materials and manufacturing cardiac stents.
-
Thin Disk Lasers
Thin disk lasers perfectly combine kilowatt-level average power with diffraction-limited beam quality. A Yb:YAG thin disk is coated on the back with a highly reflective layer for both laser and pump light, and is integrated with a heat sink via gold-tin solder or direct diffusion bonding, achieving a “gain + mirror + heat sink” three-in-one design. This design enables long-distance, high-speed scanning processing even at kilowatt-level output.
