Optical Parametric Amplifier

Optimized for Time-Resolved Spectrometry
For Ultrafast Ti:Sapphire Amplifiers
Fully Automated
apollo t opa

The Apollo-T OPA has been developed to extend the tuning range of a kHz Ti:Sapphire amplifier from the UV to the Mid-IR. It is optimized to work with Ultrafast Systems’ spectrometers. High stability and high efficiency are achieved through two-step amplification of a white-light supercontinuum, and nonlinear crystal tuning, optical delay compensation, and wavelength separation are fully computer controlled.

This OPA has been designed as a capable yet easy-to-use light source with the spectroscopist in mind. Its layout has been optimized to fit neatly alongside new or existing spectrometry systems, minimizing the amount of table space required. The inclusion of multiple frequency conversion schemes allows for computer-controlled tuning of the output wavelength, 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. Optional integrated stages for the generation of the second and third harmonics of the fundamental laser wavelength further reduce the need for external routing optics and a harmonics generator.
