Meet us in Budapest

3/10/2022

 
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).

Class 5 Photonics develops compact and brilliant extreme ultraviolet and soft x-ray laser sources for future solutions in the semiconductor market.
The most recent and future chipmaking for important technologies such as 5G and autonomous mobility is based on extreme ultraviolet (EUV) lithography. While the EUV fabrication itself is driven by massive high-tech machines of tremendous complexity, the future throughput and precision rely on fast metrology tools and next-generation photoresist materials.
Laser-driven EUV and soft x-ray sources offer unique properties for the implementation of innovative imaging tools to be applied in metrology and spectroscopy methods for chemical analysis. Further, compact interferometers and even EUV workstations for rapid prototyping are possible.

Light Beads Microscopy (LBM) with the White Dwarf OPCPA for high-speed, volumetric brain imaging

9/6/2021

 
A new microscopy approach developed by the Vaziri Lab at Rockefeller University takes the next steps for high-speed, volumetric recording of neuroactivity in the mouse cortex. The developed so called Light Beads Microscopy (LBM) is a mesoscopic imaging approach able to record up to 1 million neurons within 5.4×6×0.5 mm^3 volumes at 2 Hz frame rate.
Hence, the technology can enable neuroscientists to understand cortex-wide information processing and ultimately how the brain works.

Measurements have been performed with the White Dwarf OPCPA for multi-photon microscopy.

ELI ALPS and Class 5 Photonics tackle the next step in attosecond sources

8/31/2021

 
The Extreme Light Infrastructure Attosecond Light Pulse Source (ELI ALPS) in Szeged, Hungary and Class 5 Photonics have signed a research and development contract for the new Mid-Infrared High-Energy (MIR-HE) laser and attosecond beamline (MIR-HE ATTO) at ELI ALPS.

ELI ALPS is a research facility providing cutting-edge laser systems and secondary sources for worldwide users. The focus of the institution is on so-called attosecond light pulses, an extreme form of laser light with two remarkable properties: These light pulses have a wavelength typically in the extreme ultraviolet region from 10 - 100 nm, thus allowing observations of nanometer scale objects. Further, the short light flashes have such extraordinarily short duration that even the motion of electrons can be captured (1 attosecond = 0.000000000000000001 seconds).

Picture
With the MIR-HE ATTO source, Class 5 Photonics and ELI want to take the technology one step further: Current sources are limited in the available power and the ultimately accessible wavelength. For the first time, attosecond pulses with a wavelength shorter than 1 nm will be generated. “This project is an outstanding opportunity for Class 5 Photonics and totally within the DNA of our team.” says Dr. Torsten Golz, who is leading the project at Class 5 Photonics.

In order to reach such remarkable light properties 1000 times per second (1 kHz) a new high-energy mid-infrared laser system is being developed by Class 5 Photonics. The 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 MIR-HE laser system will additionally comprise the most advanced laser technologies, such as spectral phase-shapers, adaptive mirrors, and nonlinear spectral broadening. One of the key components is a high-power picosecond thin-disk laser provided by Trumpf Scientific Lasers in Munich, Germany, which delivers 200 mJ pulse energy at 1 kHz repetition rate. 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).

The intense mid-infrared pulses from the MIR-HE laser will be focused in a high-density gas target, specially developed by Class 5 Photonics. Here, the infrared laser pulses will be converted to soft X-ray pulses with photon energies exceeding 1 keV, corresponding to wavelengths below 1 nm. The physical process is called higher-harmonic generation (HHG). Class 5 Photonics has a team of experts who are experienced in highest power laser development and extreme ultraviolet to soft X-ray generation. Within the next two years, the team will develop not only the MIR-HE laser and the MIR-HE ATTO HHG source, but also the complete MIR-HE ATTO beamline, including the experimental end-station for cutting-edge attosecond spectroscopy techniques. First experiments are planned in 2023 in joint collaboration with ELI ALPS.

White Dwarf for 3-photon microscopy installed in bio-imaging lab in Germany

4/20/2021

 
Another White Dwarf for 3-photon microscopy was installed in a bio-imaging lab in Germany. With > 5 W and 40 fs at 1300 nm the WD-1300 provides the highest average power and peak intensity on the market for advanced microscopy applications.

Additionally, our one-box solution and robust engineering achieves excellent power stability and pulse-to-pulse stability (typically < 0.5 %). The integrated, industrial Coherent Monaco 60 W pump laser provides additional reliability and user friendly operation of the White Dwarf system.
Hence, biologists can focus on their in-vivo experiments while keeping laser maintenance to a minimum and increasing up-time.

The installed system is upgradable with a second channel at 1700 nm (WD-1300-dual). An independent, second OPCPA channel is optimized at 1700 nm and hence multi-color experiments are possible when running the system in a parallel mode (1300 and 1700 nm simultaneously). Alternatively, the user can switch between 1300 and 1700 nm to double the average power at each wavelength for deep brain imaging.
