Micro-Joule energy, mid-IR pulses with 9-cycle duration from a 100 kHz OPCPA source — •Alexander Grün¹, Olivier Chalus¹, Philip K.

Ultrashort pulsed light sources in the mid-IR are sought for numerous different fields, e.g. strong field physics, which demands high repetition-rate few-cycle pulses with stable carrier envelope phase (CEP). Generating such pulses in the mid-IR should result in shorter attosecond pulses, while broad bandwidth mid-IR pulses also cover many vibrational transitions in important molecules, opening a wide range of spectroscopic applications, e.g. medical breath monitoring.

Here we present such a completely new, scalable and potentially CEP stable source based on OPCPA, generating 9 cycle pulses at 3.2 μm with 1.2 μJ energy at a repetition rate of 100 kHz.
