WHITE DWARF OPCPA 5 W  POWERED BY COHERENT

for 3-photon microscopy

The White Dwarf is a compact and a robust laser system specially designed for 3-photon microscopy, offering now simultaneously 1300 and 1700 nm at outstanding performance parameters. With the highest peak power available for 3-photon microscopy on the market, the White Dwarf allows neuroscientists to image deeper, faster
and at better resolution than ever before at green and red fluorescent markers.

  • > 5 µJ at 1300 nm @ 1 MHz

  • > 5 µJ at 1700 nm @ 1 MHz

  • repetition rates up to 10 MHz available

  • short pulse durations < 50 fs at sample

  • pumped by Coherent Monaco industrial femtosecond laser

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.
