Er:YAG Crystals, 15%Doping, ⌀5mm

Er3+:YLF crystals are characterized by a low phonon frequency, which reduces the probability of nonradiative multiphonon relaxation, thereby increasing the luminescence quantum efficiency. The long lifetime of the laser emission level allows for higher energy storage, which is useful for Q-switched laser mechanisms. We can provide Er3+:YLF crystals in various specifications.
