The OPA 9400 and OPA 9450 are used to extend the wavelength coverage of the RegA 9000 and RegA 9050, respectively. The OPA 9400/9450 are 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. Multiple outputs are available and all beams are inherently synchronized, 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 480-700 nm, and an idler beam tunable from 930-2300 nm.
