High energy OPA system for picosecond-CARS

June 22nd, 2021

For the specific experimental requirements of our customer at Institute of Applied Physics (IAP) in Jena, we developed a customized high energy Optical Parametric Amplifier (OPA). This device is able to deliver laser pulses with over 160 µJ of energy, and has a wavelength tuning range between 700 and 940 nm. A key feature of this system is its very narrow and constant spectral bandwidth of 20 cm-1 achieved over the entire spectral range. Together with the mJ-energy of the ps-pump laser, the setup is...

A new low record!

June 17th, 2021

It’s not always about having more power. This time we were able to pump our Optical Parametric Amplifier (OPA) AVUS, with only ~ 8 W at 2 MHz, resembling only 4 µJ of energy per pulse. Even with this low energy we achieved our standard specification of the conversion efficiency > 12% at peak (Signal+Idler). Prof. Dr. Katharina Franke uses > 40 W of a Yb-laser for a sophisticated THz generation setup. The remaining power is converted with our AVUS...
