Overview
The Levante Emerald fs is a synchronously pumped, tunable OPO with high conversion efficiency, generating output wavelengths from 670 nm to 2200 nm. It is driven by green (SHG of 1 µm) mode-locked femtosecond lasers. It offers a user-adjustable bandwidth between 80 cm-1 and 160 cm-1, along shot-noise-limited performance. Applications include broadband and spectral focusing CARS / SRS microscopy, multiphoton microscopy to nonlinear spectroscopy.
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.
