Tunable Single-Frequency Pulsed Lasers

  • Ideal source for single frequency laser pulses
  • Either Ti:Sa or dye based cw systems can be used as seed for large wavelength ranges
  • Also possible: To employ diode lasers with high isolation for smaller wavelength ranges
  • Seed input power: 50 – 300 mW single frequency
  • High peak powers while ultra low amplified spontaneous emission (ASE)
  • Optional SHG/THG frequency conversion or other nonlinear conversion processes can be used

There are also optimized setups for high repetition rates available: PulsedAmp 2xHRR / 3xHRR

PulsedAmp 4x

  • Consists of four amplification stages
  • Three circulator systems with dye cells integrated in single housing

PulsedAmp 5x

  • Consists of five amplification stages
  • Three circulator systems with dye cells integrated in single housing
  • Unique performance: Dramatically suppressed ASE and cw seed beam due to phase conjugated mirror based on Stimulated Brillouin Scattering (SBS)

Performance

Using 300 mW of seed radiation and 400 mJ of pump laser energy it is possible to generate 30 mJ pulses at 730 nm (Pyridine 2). However, results depend of wavelength, seed laser and pump laser details.

The graph shows the spectral profile of the pulses. The linewidth is determined by the pulse duration and shape (Fourier-limit) of the pump laser, in this case a non-seeded YAG laser.
