You are here: Home / Fluoride Crystal / Er:YLF

Er3+:YLF crystals are characterized by low phonon frequency, which decreases the probability of non-radiative multi-phonon relaxations, therefore increases luminescence quantum efficiency. Long lifetime of laser emitting levels allow higher energy storage, which is useful for the Q-switch lasing regime. High band-gap along with low phonon energy determines very wide transparency range, which is possibly from VUV to 10μm region. Negative Er3+:YLF thermo-optic coefficient is an advantage, since it reduces thermal-lensing effect and improves beam shape as well as stability at high average pump power.
