Sirah Lasertechnik’s PulsedAmp Series comprises of tunable pulsed dye laser amplifiers for the generation of reliable tunable single-frequency laser pulses. This series is the ideal source for single frequency laser pulses, with optimized setups for high repetition rates (PulsedAmp 2xHRR / 3xHRR) or high energies (PulsedAmp 4x / 5x).

Either Ti:Sa or dye based cw systems with seed input powers of 50 mW to 300 mW (single frequency) can be used as seed for large wavelength ranges, and it is also possible to employ diode lasers with high isolation for smaller wavelength ranges. PulsedAmp lasers provide high peak powers with at the same time low or even ultra-low amplified spontaneous emission (ASE). Optional SHG/THG frequency conversion or other nonlinear conversion processes can be applied.

Using 300 mW of seed radiation and 80 W (PulsedAmp 2xHRR), 150 W (PulsedAmp 3xHRR) or 400 mJ (PulsedAmp 4x, 5x) of pump laser energy, it is possible to generate 8 W (2xHRR), 15 W (3xHRR) or 30 mJ (4x, 5x) pulses at 730 nm (Pyridine 2). However, results depend on wavelength, seed laser and pump laser details. The linewidth is determined by the pulse duration and shape (Fourier-limit) of the pump laser. PulsedAmp 5x systems feature a phase conjugated mirror based on stimulated brillouin scattering (SBS), resulting in dramatically suppressed ASE and cw seed beam.

Key Features:

  • Nanosecond Pulsed
  • Single Frequency
  • Wavelength Range: 198 to 900 nm
  • Repetition Rate: 1 to 150 Hz
