Supernova OPCPA at 2 µm for water-window HHG to investigate challenges in modern chip-making

11/24/2020

 
A new few-cycle, high-power OPCPA at 2 μm wavelength and scalability to 100 W average power with mJ pulses is built by Class 5 Photonics for a new brilliant soft X-ray source at the Advanced Research Center for Nanolithography (ARCNL) in Amsterdam.

Our CEO Robert Riedel presented the status of this project at the OSA High-brightness sources conference (see video).
The motivation behind the work becomes clear by taking a look at modern chipmaking, enabled by EUV lithography at 13.5 nm wavelength.

Femtosecond OPCPAs from XUV to MIR for ultrafast dynamics experiments - a brief overview

7/31/2020

 
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

Our first White Dwarf OPCPA shipped to Korea

4/3/2020

 
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).

THz generation in organic crystals with the White Dwarf HE

10/18/2019

 
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.
