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.
Benefits
- 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
