Light Beads Microscopy (LBM) with the White Dwarf OPCPA for high-speed, volumetric brain imaging9/6/2021
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 3-photon microscopy. Reference: Demas, J., Manley, J., Tejera, F. et al.

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).
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.
Class 5 Photonics will be present at the "Nonlinear Optics" topical meeting by OSA.
An international forum for discussion of all aspects of nonlinear optics, including new phenomena, novel devices, advanced materials and applications. Join our Scientific talk about our Moonlander HHG source:
Class 5 Photonics moved to a new office and lab space. We are very happy to be now at the Start-Up Labs Bahrenfeld (slb.hamburg) just next to the DESY campus. The new office and lab space will allow us to grow even further and is a perfect enviornment for young high-tech companies. Our new address is: Luruper Hauptstraße 1, 22547 Hamburg. You can access our building from Luruper Hauptstraße (Bus line 3/X3/2, station »Stadionstraße«) or from the DESY campus for deliveries (building 98, Notkestr 85, 22607 Hamburg).

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.
Our CTO Michael presented at Photonics West 2021 our high-power OPCPA system for in vivo multi-photon microscopy: White Dwarf OPCPA. The White Dwarf OPCPA is a compact and robust laser system especially designed for multi-photon microscopy at high performance parameters.
