Our CTO Michael presented at the SPIE Photonics West 2020 conference our latest developments: A dual
channel laser system with gap-less tuning from 250 to 1300 nm at megahertz repetition rates for time resolved photoelectron emission microscopy and spectroscopy.
Based on the success story of our White Dwarf OPCPA with high performance operation at a single wavelength, we now also provide tunable solutions for demanding spectroscopy and microscopy applications.
Ultrashort pulses (< 30 fs) are delivered in a spectral range from 650 to 1300 nm. This makes the White Dwarf WD-800-tunable the most flexible non-colinear OPA on the market.
Additionally, the wavelength range can be further extended to the UV via second harmonic (SHG) and third harmonic generation (THG). Due to our gap-less approach, material scientists have access to the green wavlength range (500 nm) and can, for example, study the transport of carriers excited by a green pump pulse.
Equipped with two outputs, our White Dwarf WD-800-tunable-dual offers two synchronized channels and enables pump-probe studies.
Thus, time-resolved ARPES or PEEMS benefit from our very flexible solution while maintaining high temporal resolution to study ultrafast dynamics in materials.
Our White Dwarf WD-800-tunable can operate at 1, 2 or 4 MHz for fast image acquisition and to
suppress space charge effects. A pulse-picker of the integrated pump laser (Coherent Monaco 60 W incl.) can be used to reduce the repetition rate in alignment mode or for lower average power operation.
EPIC interviews our CEO Robert - class 5 photonics' Journey to Provide ground breaking technology for industry and science
CTO Jose Pozo of EPIC (European Photonics Industry Consortium) interviewed our CEO Robert Riedel who shared some insights of Class 5 Photonics' journey from the early beginnings to the future.
Robert explains why Class 5 Photonics provides the most powerful OPCPA systems on the market and how Class 5 Photonics pushes lasers to extreme wavelengths at extreme average power. A clear mission to change industry and to provide ground breaking technology to enable researchers to push new limits enhances our success and enabled the company to grow to now 11 employees.
Robert gives deep insights about how to grow a former research group to an effective small company, struggles and our deep motivation to contribute in the exciting ultrafast research field.
Thanks EPIC for this great interview!
You are coming to DESY Photon Science and European XFEL Users' Meeting 29-31 January 2020?
We are exhibiting on Friday at booth K11 and are looking forward to explain you our latest news from our high power OPCPA systems. Also, don't miss our poster about the SUPERNOVA OPCPA with up to 100 W average power at 800 nm, 1550 nm and 2 µm.
Merry Christmas and a happy new year wishes the Class 5 Photonics Team.
It was an exciting year 2019 with many diverse and interesting projects. We built and installed laser systems for a vast scientific community from multi-photon microscopy, ultra-fast material science to attosecond science covering products from 5 W to 100 W average power.
Our team grew by four more employees to support our deep expertise in laser science and ultrafast applications as well as sales and marketing.
We look forward to new challenges and new exciting projects in 2020 to serve the ultrafast scientific community!
We congratulate Thorlabs to the acquisition of OPA technology for 2- and 3-photon-microscopy from KMLabs. This clearly shows the strategic importance of this rising field of research. At Class 5 Photonics, we are contributing to this field with award-winning high-power laser technology, enabling novel fast volumetric neuronal imaging techniques.
Within our partnership with Coherent (Santa Clara), we offer and have sold the White Dwarf OPCPA at imaging wavelengths of 960, 1300 and 1700 nm (multi-output) and as few-cycle versions at 800 nm and 2000 nm (multi-output) with µJ pulse energies at record repetition rates up to 10 MHz and unprecedented pulse-to-pulse-stability and reliability.
Owing to their high second-order nonlinear susceptibility, organic crystals have gained tremendous interest as THz generators within the scientific community. Recently, high-field THz generation in several organic crystals have been demonstrated by various research groups. The velocity phase matching condition is achieved using collinear propagating geometry. The phase matching condition is best fullfilled when the pump wavelength is in the IR range from 1400 nm to 1700 nm. The absorption of the pump light in the crystals is reduced in this wavelength region, leading to an increased damage threshold, which enables higher pump fluences and hence a higher conversion efficiency.
Our compact and versatile White Dwarf HE laser system is extended to a tunable, high power version centered at a wavelength of 1.55 µm with a pulse duration of < 36 fs making it an optimal source for THz generation with organic crystals.
In addition, an optically synchronized compressed probe pulse with a pulse duration of < 15 fs at 850 nm is available as a second output channel.
The White Dwarf HE is available with 10, 20 or 30 W output power.
We are already looking forward to Photonics West 2020 in San Francisco!!
As usual, we can be found in the German Pavillon together with a lot of other innovative, young companies. Meet us there at booth number 4545-40 and we show you our latest developments and updates of our powerful OPCPA systems.
Also we are excited to be sponsor of the Ultrafast Phenomena and Nanophotonics session. The latest scientific results about ultra-fast material science, THz spectroscopy, plasmonics and nanophotonics will be shown and discussed here.
We are honored to present results about our "Femtosecond OPCPAs from UV to short-wave-IR wavelengths for ultrafast dynamics experiments from condensed matter to atoms, molecules, and clusters" in the Ultrafast Optical Techniques session lead by Giulio N. Cerullo. Don't miss it!
UPDATE - our scientific talks:
Class 5 Photonics is a Silver sponsor at Ultrafast Optics XII, which will be held October 6–11, 2019 in Bol on the Island of Brač, Croatia.
We will present a poster and a commercial talk on Monday evening about our 100 W-level Supernova OPCPA providing extreme average powers and outstanding performance combined with stable operation.
Also don't miss the talk on Monday 5 pm about "High power, 100 kHz repetition rate OPCPA operating at 800 nm and 1.5 – 2.0 µm" from staff scientist at SLAC!
Additionally, the White Dwarf OPCPA can be configured for three-photon excitation of red fluorescent proteins at 1700 nm. Pulse energies of more than 2 µJ at 1 MHz repetition rate allow fast imaging of deep-tissue.
The White Dwarf OPCPA implements the Coherent Monaco industrial fiber laser as pump source for long-term stability, reliability and turn-key operation.
