The APOLLO-Y Optical Parametric Amplifier has been developed to extend the tuning range of an ultrafast Ytterbium amplifier from the UV to the NIR. It is optimized to work with Ultrafast Systems’ spectrometers – Helios, Eos, Halcyone, etc. High stability and high efficiency are achieved through three-step amplification of a white-light supercontinuum, and all nonlinear crystal tuning, optical delay compensation, and wavelength separation is fully computer controlled. This OPA has been designed as a capable yet easy-to-use pump source with the spectroscopist in mind. Its layout has been optimized to fit neatly alongside new or existing spectroscopy systems, minimizing the amount of bench space required. The inclusion of multiple frequency conversion schemes allows fully computer-controlled tuning of the output wavelength from 258 nm to 2600 nm, while collinear output from a single port reduces the need for external beam routing optics. The timing of the pulse output remains consistent across the whole wavelength tuning range.
