Abstract

Broadband ultrashort MIR sources are of particular relevance for linear spectroscopy in applications such as pollutant detection or cancer diagnosis. Indeed, their broad bandwidth allows for a simultaneous detection of several absorption lines, thus avoiding the need for scanning schemes. More recently, nonlinear spectroscopy [1] or strong field driven phenomena [2] are benefiting from in ultra-intense MIR sources due to their high peak power and long wavelength. However, high repetition rate is needed for good signal-to-noise detection in reasonable acquisition time.
