White Dwarf dual

Laser for 3-photon deep-tissue imaging with red and green markers

wavelength: 1300 nm and 1700 nm
average power: > 3 W or > 5 W
optimized for multicolor deep imaging
based on industrial Yb-fiber femtosecond laser

Introduction

High performance femtosecond laser for three-photon microscopy (3p microscopy)

The White Dwarf is a femtosecond laser system specially designed for three-photon microscopy offering highest performance and robustness.

The White Dwarf is a compact and robust femtosecond 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, the White Dwarf allows neuroscientists to image deeper, faster and at better resolution than ever before at green and red fluorescent markers.

FAQ

Do you have customer references?

Yes, the White Dwarf is already installed and tested by many labs. Please contact us, we are happy to share specific references to your application. You can find a first overview of scientific publications from our users below.

How many outputs does the White Dwarf dual provide?

The White Dwarf dual can offer up to three outputs: 1300 nm, 1700 nm and 1035 nm. The system can be designed to offer all outputs simultaneously or switchable between different outputs. Please contact us for customization options.

At which repetition rate does the White Dwarf dual operate?

Our White Dwarf dual version can be configured at any single repetition rate between 1 and 2 MHz. The maximum average power is available at the configured repetition rate. Lower repetition rates can be chosen using the built-in pulse-picker. This provides a constant pulse energy at correspondingly lower average power. Example: WhiteDwarf operating at 2 MHz and 2.5 µJ delivers 5 W; it can be down-picked to 1 MHz and 2.5 µJ delivering 2.5 W.

Who installs the White Dwarf?

Our service team will install the pump laser and the OPCPA at the customer’s site. Users will receive training on the operation of the White Dwarf.

Is the pump laser included in the White Dwarf?

Yes, we offer the full package including pump laser and OPCPA. The pump laser is integrated into the OPCPA housing on a shared thermally managed breadboard offering a robust one-box solution.
