Description
Yb YAG Laser Crystal is a laser-active material. It is more suitable for diode-pumping than traditional Nd-doped systems. It pumps at 0.94 um with high optical quality, high slope efficiency, and low fractional heating across broad absorption bands. The dopant is ytterbium.
Yb YAG Laser Crystal vs Nd:YAG
Compared with YAG(Nd), the absorption bandwidth is much larger. Thermal management requirements for diode lasers drop. Upper-state lifetime runs longer. Thermal loading per unit pump power is three to four times lower. The same pump power yields more laser with less heat. A diode-pumped design can run with simpler cooling. The broad bands relax tolerances on diode wavelength selection.
Yb YAG Laser Crystal thermal edge
Low fractional heating is the core advantage: less pump energy becomes waste heat. Broad absorption bands tolerate diode wavelength drift. High optical quality keeps beam quality high at power. Thin-disk and high-power rod geometries both benefit. The longer upper-state lifetime improves energy storage for Q-switched pulses.
Typical applications
High-power diode pumped lasers. High efficiency, high average power LD pumped lasers. Industrial cutting and welding lasers adopt Yb for efficiency. For the neodymium classic, see our Nd YAG Laser Crystal.
