We produced this video based on an idea to share for #dayofphotonics some insights into our work and people. The short video was produced solely by ourselves. Some director skills, creative story-telling and video cutting know-how within our team got revealed. Most of the scenes were filmed as they happened and show an authentic, exciting day at Class 5 Photonics.
Meet us at our virtual exhibit and join Robert's talk about "Few-cycle OPCPAs at 2 μm".

Class 5 Photonics is very motivated to try out this cool online platform which gives rise to new possibilities for participants, speakers and exhibitors to engage and connect with each other.
Online conferences and exhibitions will reach - also after Covid - a wider community and give them access to exciting scientific and technical content. Online events enable participants from all over the world to connect despite their travel budget, work situation and restrictions while reducing CO2 emissions. Let's hope we can use this to learn for the future! Get in touch with us at FiO+LS conference on the virtual exhibition platform. A 1:1 chat and a group chat will be available to get directly in contact with us. Let us know your feedback! Ask questions! Watch Robert's (CEO) recorded talk about high-power OPCPA systems! Looking forward to hear from you! Ultrafast dynamics experiments in physics, chemistry and biology, in condensed matter or gas phase require different types of ultrafast laser sources. Class 5 Photonics builds high-power optical parametric chirped pulse amplifiers (OPCPA) which are a powerful toolbox to deliver femtosecond pulses from the XUV to MIR spectral range.

Some good news and some bad news… Just before the coronavirus disease arrived to Europe Class 5 Photonics shipped its very first system to Asia - namely South Korea. We are proud to reach the Asian market and to serve scientists world-wide with our high-power OPCPA systems made in Germany. The shipped White Dwarf OPCPA is a compact (80 cm x 80 cm) one-box laser system incorporating a 40 W Coherent Monaco industrial laser and the Class 5 Photonics' high-power optical parametric chirped-pulse amplifier (OPCPA). This unique combination provides turnkey access to few-cycle pulse widths < 9 fs at 800 nm, with pulse energies > 4 μJ and 1 MHz repetition rate, featuring excellent long-term output stability. The White Dwarf system is ideal for applications ranging from attosecond science to ultrafast electron diffraction and multidimensional spectroscopy. Our little package already arrived at Korea and now the system is waiting for its installation in the Customer's lab. Unfortunately, the current situation of world-wide Corona infections, quarantine and travel bans will postpone the installation. We are patient until then and look forward to rock the customer’s new lab when the White Dwarf OPCPA gets finally installed (we keep you posted).

UPDATE: This conference got cancelled. We are going to present the latest results of our 100 W-level Supernova OPCPA at DPG Tagung in Hannover. Come and discuss with us about extreme power at extreme wavelength. Unfortunately, we will not be present with a booth this time, but we are anyway around and are looking forward to some interessting discussions about high-power femtosecond lasers and applications. See you there! 
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:
