Tunable UV lasers

Home → Tunable UV lasers

Family of solid-state UV lasers with laser pump. Active media of those devices amplify light of UV spectral range. Achieved laser emission is not a result of nonlinear conversion.

Physical principles

Yang and DeLuca, Appl.Phys.Lett., 31, 594 (1977)

  • Lasing transitions – 5d-4f transitions of Ce3+ ions in fluoride crystals
  • Electrical-dipole allowed
  • Localized in UV and VUV spectral ranges
  • High fluorescence quantum yield
  • Wide bands (40 nm due to vibronically broadened)
  • Significant Stokes shift
  • High values of working transitions cross-sections
  • Degradation excluded of active medium due to wide band-gap and inhibition of photodynamic processes.


  • Continuous tuning in the ranges 284 nm – 315 nm and 305 nm – 335 nm (according to active element)
  • High stability of laser emission parameters
  • Operation at high repetition rates (Hudreds of kHz)
  • Short pulses generation option (hundreds of picoseconds)
  • Short pulses amplification (femtoseconds)
  • Independent on temperature, no cooling needed
  • Low cost of tuning automation (+ 20 % of price)
  •  Easy to use
