1 mJ | 15 fs | 100 W

The Future of Laser Amplifers

We provide high power femtosecond lasers based on a modular optical parametric chirped-pulse amplification (OPCPA) system. Our designed OPCPA systems and upgrade modules can be customized to fit your experimental or industrial needs. The offered laser parameters range from μJ | MHz to mJ | kHz achieving even Terawatt peak power at average power up to 100 W. The pulse durations range from few-cycle (8 fs), over ultrashort (15 fs) to long pulse (30+ fs).

Using industrial picosecond lasers as pump sources and our reliable white light seeder, Class 5 OPCPA systems achieve shortest femtosecond pulses at superior long-term stability.

Class 5 Photonics is a spin-off company of DESY (Deutsches Elektronen-Synchrotron) and Helmholtz Institute Jena. Class 5 Photonics is winner of the Start-up Challenge prize organised by OptecNet Deutschland e.V.

OPCPA is the future enabling technology; providing tunable, femtosecond pulse duration, and high power (product of repetition rate times pulse energy), thereby making it possible to reduce experimental or industrial processing times by a factor of 10-100, compared to conventional titanium-sapphire technology.

As a reference customer, we are providing the design and implementation of a Joule-class femtosecond laser system for Queen's University Belfast, Northern ireland. Further, we provided a conceptual design the Extreme Light Infrastructure - Attosecond Light Pulse Source, in Hungary (http://www.eli-hu.hu/).

White Dwarf OPCPA
Benchmark in its Class

Ultrafast optical parametric chirped-pulse amplifier.

The White Dwarf alpha OPCPA series provide pulse energies from 1 - 10 μJ. The internal repetition rate can be chosen within 0.1 - 4 MHz and the maximum average output power is 20 W.

The White Dwarf gamma OPCPA series provide higher output pulse energies of up to 200 μJ at 20 W.

All products can be configured with optional modules. We offer CEP stable output, wavelength tunability (visible, near-infrared, infrared), few-cycle mode (8 fs), ultrashort mode (15 fs), long-pulse mode (30 fs), phase shaper, and second- and third-harmonic generation modules.

Supernova OPCPA
High average power above 100 W

The Supernova OPCPA system is designed for high average power above 100 W, delivering pulse durations ranging from <15 fs (broadband) to 100 fs (wavelength-tunable). Using a commercial high end kW-class pump laser system, we supply the Supernova OPCPA as a customer-specific development project. Using our White Dwarf OPCPA front-end module with integrated white-light source ensures reliable operation of the system. The system includes a high power frequency doubler (SHG), an efficient stretcher-compressor design and three noncollinear optical parametric amplifier (NOPA) stages.

The Supernova HE OPCPA system is designed for high energy, high average power operation. Pumped by high-end kW-class thin-disk lasers, these system provide Terawatt peak powers (10 mJ, 10 fs) at up to 10 kHz repetition rate.
