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).  Proud Laser Engineers a few weeks ago with packaged White Dwarf OPCPA system.
Customer lab in South Korea with White Dwarf OPCPA waiting for its installation. Normalized spectral intensity: White Dwarf OPCPA WD-800, central wavelength ca. 800 nm, 4 W average power, 1 MHz repetition rate, Pump laser Coherent Monaco 40 W. Retrieved temporal intensity profile measured via SHG-FROG: White Dwarf OPCPA WD-800, central wavelength ca. 800 nm, pulse duration FWHM 8.9 fs, 4 W average power, 1 MHz repetition rate, Pump laser Coherent Monaco 40 W.
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. |
