Class 5 Photonics GmbH: White Dwarf HE OPCPA pump-probe suite for time-resolved ARPES

Abstract

The White Dwarf HE OPCPA is a high-performance laser system with ultrashort pulse durations covering different wavelength versions from UV to mid-IR. Additionally, a second OPCPA output at high temporal contrast is used for efficient higher harmonic generation (HHG) to provide 21 eV coherent XUV for tr-ARPES. This makes the White Dwarf HE OPCPA combined with our brand new Moonlander HHG source a powerful, robust pump-probe suite, and scientists can take the next step with their ultrafast pump-probe studies. In our product showcase we present a customer configuration for THz pump and XUV probe experiments at high repetition rate of 100 kHz. Additionally, the White Dwarf HE OPCPA can be configured at other pumping wavelengths from UV to mid-IR. The Moonlander HHG provides robust operation and high photon flux at 21 eV with scalability up to 50 eV. The combination of our White Dwarf HE OPCPA with our brand new Moonlander HHG offers a unique full pump-probe suite for time-resolved studies.
