Overview
The OPO-X fs is a synchronously pumped, tunable OPO with high conversion efficiency in the IR-range, generating output from 1000 nm to 4 µm. It is driven by mode-locked femtosecond Ti:Sa lasers and its design allows independent wavelength tuning of the Ti:Sa laser and OPO. Intracavity second-harmonic generation (SHG) within the OPO enables efficient conversion into the VIS-range. Combined with harmonic generators for the Ti:Sa laser extending down to the 4th harmonic, the systems can be configured from 190 nm to 4 µm, providing 200 fs pulses and shot-noise-limited performance. It is ideal for nonlinear and time-resolved spectroscopy, multiphoton microscopy and pump-probe experiments. If the Ti:Sa pump laser is convertible between femtosecond and picosecond operation, this flexibility is also available for the OPO-X.
Systems can be further customized using pulse pickers (pulseSelect) to reduce the repetition rate, spectral slicers (pulseSlicer) for bandwidth reduction, optical delay lines (scanDelay) and dispersion compensators (femtoControl). Multiple OPOs can also be pumped simultaneously by a single pump laser to generate independent, tunable, and temporally synchronized pulses.
Customization is our specialty. If your requirements are not listed in the specification table, please feel free to contact us.
