Product Description

Er:YLF Laser Crystal




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.




  • A low phonon frequency
  • Long lifetimes of the laser emitting levels
  • Wide transparency range (from the VUV to the 10 μm region)
  • Negative thermo-optic coefficient
  • Custom crystals available upon request





  • CW and Q-switched ~3 μm lasers for oral surgery, dentistry, implant dentistry, and otolaryngology
  • Up-conversion visible lasers for display technology, medicine (diagnosis and treatment)
