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.

The Supernova OPCPA power amplifier is designed for boosting your White Dwarf OPCPA average power to 100 W with 1 mJ pulse energy at 100 kHz repetition rate (example). In the Supernova HE version, even 10 mJ at kHz repetition rates are possible, providing you a high repetition rate terawatt laser with 10 fs pulse duration. Using a commercial high end kW-class pump laser system, we supply the Supernova OPCPA as a customer-specific development project.

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), dual output channel for dual color experiments, phase shaper, and second- and third-harmonic generation modules.

Quasar infrared OPCPA
High average power above 100 W

Our new Quasar infrared OPCPA system operates in the wavelength range of 1.4 - 1.6 μm, delivering pulse durations shorter than <100 fs. It is based on the robust White Dwarf OPCPA platform, but uses the fundamental pump beam at 1030 nm. Product options are: passive CEP stabilization, wavelength tunability, mid-IR operation at 3 μm and frequency conversion (SHG, THG, DFG). With a special dual output option combined with the DFG module, the wavelength range can be extended beyond 10 μm.

Ask for our Supernova OPCPA power amplifier for the Quasar infrared OPCPA system with average power beyond 100 W.
