Time-resolved ARPES
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 can be used for efficient higher harmonic generation (HHG) to provide 21 eV coherent EUV for tr-ARPES.

This makes the White Dwarf HE OPCPA combined with our brand new HHG source a powerful, robust pump-probe suite, and scientists can take the next step with their ultrafast pump-probe studies.
The White Dwarf HE OPCPA is a powerful femtosecond optical-parametric chirped-pulse amplifier system. It comes as a complete system in different power levels, pumped by an industrial Yb:fiber or Yb:YAG laser, making it robust, reliable and easy-to-use. The different wavelength versions covering the near- to mid-infrared range open a wide field of applications. All versions can be combined to a dual output pump-probe suite with different pulse properties in pump and probe and intrinsic synchronization.
