Single-shot, high repetition rate detection of the Carrier-Envelope-Phase of ultrashort laser pulses

Project: Research

Project Details

Description

The interaction of short laser pulses with matter often depends on the Carrier-Envelope-Phase (CEP), which is the offset between the maximum of the electric field and the envelope of the pulse. For high-repetition-rate laser systems, this phase can usually only be measured as an average quantity. We propose a novel analog method to measure the CEP of ultrashort laser pulses in single-shot and for every laser shot at high repetition rate (hundreds of kHz to MHz). While conventional approaches use slow array detectors and computationally expensive calculations, we perform the measurement via optical Fourier transform, virtually not imposing any speed limitations. The approach also opens up for new avenues for CEP-stabilization, possibly making most of today’s complicated and expensive stabilization equipment obsolete. A patent application, securing our IP has been submitted and an article has been published.
The project will be conducted together with our long-standing commercial partner, Sphere Ultrafast Photonics. Sphere has a strong position on the ultrafast laser market, defining an efficient path for commercialization.
