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...
