Overview
The OPO-X ps is a synchronously pumped, tunable OPO with high conversion efficiency into the IR-range generating output from 1000 nm to 4 µm. It is driven by mode-locked picosecond Ti:Sa lasers and its design enables independent wavelength tuning of Ti:Sa laser and the OPO. Intracavity second-harmonic generation (SHG) within the OPO enables efficient conversion into the VIS-range. It provides 2 ps pulses, along 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 picosecond and femtosecond 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 and optical delay lines (scanDelay). 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.
