Yb:YAG(Ytterbium-doped Yttrium Aluminum Garnet) is a material that suitable for diode-pumping high power lasers. Yb3+:YAG crystals have 950 μs lifetime of 2F5/2 ytterbium energy level and quantum defect of only ~9%. Yb:YAG crystals also have a broad pump band at near 940 nm that is more than 10 times broader than the 808 nm pump line of Nd:YAG crystals. It makes Yb:YAG systems less sensitive to thermal shift of pump diodes wavelength. Yb:YAG lasers emit typically at either 1030 nm (strongest line) or 1050 nm. It is often used in powerful and efficient thin-disk lasers.
Advantages:
  • High slope efficiency
  • Broad absorption bands, about 8nm@940nm
  • Conveniently pumped by reliable InGaAs diodes at 940nm
    or 970nm
  • Very low fractional heating, less than11%
  • Broad absorption bands, about 8nm@940nm
  • High thermal conductivity and large mechanical strength
  • No excited-state absorption or up-conversion
  • Yb:YAG is expected to take the place of Nd:YAG for high power diode-pumped lasers.
