See you at EQEP!

November 26th, 2024

The countdown is on! This Thursday marks the start of the 10th International Workshop on Engineering of Quantum Emitter Properties (EQEP) at the Universität Innsbruck. Our colleague Matthias Baudisch will be at the APE exhibition booth, showcasing the APE picosecond excitation source for quantum dot single-photon and entangled photon generation.Product Link: https://www.ape-berlin.de/en/quantum-dot-single-photon-generation-source/ This unique conference on quantum systems brings together leading scientists and talented young researchers. Together we discuss exciting topics such as: 🔬 Light-matter interactions and nanospectroscopy 💡...

APE celebrates its birthday!

November 14th, 2024

Exactly 32 years ago, APE was founded by Jan Popien, Edlef Buettner, and Thomas Lindemann. Together, they invented the first commercially available autocorrelator, making it possible to measure the shortest light pulses. We didn’t stop with our first product. Today, we offer over 30 products, from spectrometers to harmonic generators and from pulse compressors to quantum-dot single-photon sources.Here at APE, we’re incredibly proud of the meaningful impact we’ve made in science, working alongside the world’s leading laser manufacturers and top...

Did you know? Deeper Insight in Autocorrelation Measurements …

November 5th, 2024

In their latest research, Torben Fiehler, Clara Saraceno, Günter Steinmeyer, and Ulrich Wittrock show in detail how you can prevent misinterpretations of autocorrelation measurements. Spectrally broad laser radiation from continuous wave (cw) lasers can produce second-order autocorrelation traces that closely resemble those of mode-locked lasers. By using the APE pulseCheck autocorrelator, the authors compared measured autocorrelations and calculations of a mode-locked Ti:Sa laser with a spectrally broad, monolithic cw Ti:Sa laser, devising a new method to safeguard against autocorrelation...
