Introduction

High performance laser for two-photon and three-photon microscopy

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

The White Dwarf is a compact and robust laser system specially designed for multi-photon microscopy, offering now simultaneously 960 and 1300 nm at outstanding performance parameters. With the highest peak power available for hybrid multi-photon microscopy, the White Dwarf allows neuroscientists to image deeper, faster and at better resolution than ever before.

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 hybrid provide?

The White Dwarf hybrid can offer up to three outputs: 960 nm, 1300 nm and 1035 nm. The outputs can be configured to operate simultaneously or to be switchable. Please contact us for customization options.

At which repetition rate does the White Dwarf hybrid operate?

Our White Dwarf hybrid version can be configured at any single repetition rate between 1 and 5 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: White Dwarf 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.
