The OPA9400 and OPA9800 are used to extend the wavelength coverage of the RegATM9000 and RegA9050, respectively. The OPA 9400/9800 are highly efficient and simple-to-use, passive devices. Microjoule pulses from the RegA are split into two beams. One produces white-light continuum seed pulses, which are amplified in a BBO OPA crystal by blue, second-harmonic pump pulses generated by the remaining pump beam.
- Wide spectral coverage from UV to IR
- Ease of use
- Variable repetition rate
- Multiple output beams
- Frequency-doubling option
Multiple outputs are available and all beams are inherently synchronised, because they originate from the same pump pulse. Tuning involves a simple manual adjustment of the OPA crystal and a delay line.
The main outputs consist of a signal beam tunable from 480-700nm, and an idler beam tunable from 930-2300nm.
