Bio imaging

Volumetric imaging at high resolution / larger imaging volume and higher frame rates by higher repetition rate / deep tissue penetration in all spectral windows / highest multiphoton signal and better signal-to-noise ratio with shorter pulses at lower heat load

Volumetric imaging of deep brain tissue

The high average power of the White Dwarf OPCPA allows imaging of brain tissue - beyond 1 mm  - in a large volume while maintaining single-cell resolution.

Our White Dwarf OPCPA powered by Coherent has its pump laser already on board to enter the next level of stability. We integrate the Coherent Monaco industrial femtosecond laser on a small footprint with state-of-the-art White Dwarf OPCPA technology to bring industrial performance to scientific output parameters.

This White Dwarf version is especially designed for multi-photon microscopy at high performance parameters. The highest peak power available for three-photon microscopy on the market allows neuroscientists to image deeper and at higher speed.
