Class 5 Photonics will be at the High-Brightness Sources and Light-Driven Interaction Congress in Budapest, Hungary from 23rd to 25th March 2022.
Meet us at our booth and join the talk of our project leader Dr. Torsten Golz about the the ELI-ALPS MIR-HE Laser System - Design and Status (MTh5C.3) on 24 March 15:15 - 15:30h.

The ultimate goal of Class 5 Photonics and ELI-ALPS is to generate via higher harmonic generation (HHG) attosecond pulses with a wavelength shorter than 1 nm at 1 kHz operation. In order to reach such extreme light properties a new high-energy mid-infrared laser system is being developed by Class 5 Photonics. This MIR-HE laser is an optical parametric chirped-pulse amplifier (OPCPA), a method to generate ultrashort pulses at different wavelengths and the specialty of the Class 5 Photonics team for more than ten years. The final output specifications of the MIR-HE laser are 3 μm wavelength, 20 mJ pulse energy, 1 kHz pulse repetition rate and 25 fs pulse duration with stable carrier-envelope phase (CEP).

Active carrier envelope phase (CEP) stabilization in the few-cycle regime is essential for most attosecond experiments. We present an optical parametric chirped-pulse amplifier (OPCPA) design providing CEP stable, sub 9 fs pulses with a dual channel output around 800 nm center wavelength and 2 µm as a high-harmonic driver for attosecond experiments.
The system is commercially available as White Dwarf OPCPA.

Our project leader Katja presents a scientific talk about this system at "DPG-Frühjahrstagung der Sektionen Atome, Moleküle, Quantenoptik und Photonik" (DPG SAMOP). Join us on Tuesday 10.45 am.
