Quantum-enhanced nonlinear microscopy

July 7th, 2021

Congratulations to Catxere A. Casacio and Prof. Warwick Bowen of the University of Queensland Australia for his publication in Nature – “Quantum-enhanced nonlinear microscopy”. The Queensland Quantum Optics Lab (Link) is the first to use squeezed light to break the shot-noise limit in Stimulated Raman Scattering (SRS). This is a breakthrough, as it enables the imaging of biological structures in an innovative way.We are proud to mention that our Optical Parametric Oscillator (OPO) the Levante Emerald ps was one of the...

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...

Levante IR fs OPO for 50 MHz

May 25th, 2021

Another great example of how flexible our Optical Parametric Oscillator (OPO) really is. Recently, we have successfully paired our Levante IR fs OPO with Coherent Monaco at University of Tsukuba, Japan. Special in this case is the fact that the Monaco pump laser runs at 50 MHz, which was a novel combination with one of our OPOs. To extent the tunable wavelength range of the OPO, we installed an additional harmonic frequency converter, our HarmoniXX THG, unfortunately not visible in the...

Light Source for Integrated Quantum Photonics

May 19th, 2021

This is what a working place looks like when the installation is almost finished.Edlef and Tobias had the pleasure to visit the Integrated Quantum Photonics Group (IQP) at HU Berlin.https://www.physics.hu-berlin.de/en/iqp This group, led by Prof. Tim Schröder has recently received brand new equipment from APE. Our experts successfully installed an OPO-X VIS, a pulseSelect and two pulseSlicers. Thanks to the IQP team for hosting us – we are looking forward to exciting results and our continued collaboration. We’ll stay tuned...

Picosecond Laser picoEmerald at Zhejiang University

June 10th, 2020

Delivery and commissioning of larger laser systems usually require highly qualified engineers to install such equipment. Customers must be able to rely on manufacturers sending engineers to any place in the world for installation and commissioning. However, the current pandemic situation and the associated travel restrictions have significantly impaired this actually common way of working. Professor Delong Zhang of Zhejiang University (China) was concerned that a planned installation of a new high-performance laser system in his laboratory could not take...

OptoScope

May 15th, 2018

“Optoscope” is a new joint research project of the APE GmbH and the Max Born-Institute for Nonlinear Optics. It is about increasing the sensitivity of pulse measuring instruments as well as providing pulse measurement techniques with new algorithms which deliver accurate results in real-time even in case of noise and complicated pulse shapes. In the last few years areas of application and the market for ultrafast lasers in the femto- or picosecond range have increased. From highly complex research assemblies...
