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 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 energies available: PulsedAmp 4x / 5x
PulsedAmp 2xHRR
- Consists of two amplification stages
- Two circulator systems with dye cells integrated in single housing
- Additional amplifier for high-energy systems available

Performance
Using 300 mW of seed radiation and 80 W (2xHRR) / 150 W (3xHRR) of pump laser energy it is possible to generate 8 W (2xHRR) / 15 W (3xHRR) 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.
