Introduction

Few-cycle OPCPA for fundamental research

The White Dwarf HE OPCPA is a high-performance laser system with few-cycle pulse durations available with different central wavelengths ranging from 800 nm to 9 µm.

We offer ultrafast, high-power and high-repetition rate laser systems to push new frontiers in ultrafast science. Our main technology platform are robust optical parametric chirped pulse amplifiers (OPCPA) delivering femtosecond pulses at extreme power for extreme wavelengths from UV to mid-IR. The White Dwarf HE series is specially designed and engineered to drive secondary light sources such as high harmonics generation (e.g. the Moonlander-HHG) or THz generation.

FAQ

Do you offer additional wavelength options?

Yes, we can customize the White Dwarf HE to meet your requirements. Please conact our sales team for futher information.

Do you include the pump laser?

Yes, the Yb-based pump laser is included in our package. We collaborate with the main providers of Yb-based pump lasers to pump our OPCPAs.

Can I use the White Dwarf HE to drive the Moonlander HHG source?

In our Moonlander HHG source the driving laser is directly included and we consult about the best driver wavelength, pulse duration and power.
