Extreme nonlinear optics using strong mid-infrared laser pulses

Abstract

We investigate t he ex treme nonlinear optical phenomena using mid-infrared pulses: 1) the laser filamentation in ambient air, pumped by a 2 μm kHz source, for atmospheric chemical detections and 2) the high-harmonic generation i n s olids, dr iven by sub-cycle 2.5–9.0 μm pulses, towards petahertz electronics.
