Feasibility study for few-cycle optical parametric chirped pulse amplication at mid-IR wavelengths

The generation of few-cycle, carrier envelop phase (CEP) stable pulses in the mid-IR is of great interest for many applications, ranging from medical and industrial applications to spectroscopy and strong field physics. Mid-IR lasers can produce shorter attosecond pulses and allow improved discrimination between tunnelling and multi-photon processes. In this work, The authors simulate the generation of such pulses via optical parametric chirped pulse amplification (OPCPA), which supports arbitrarily high repetition rates, is in principle CEP-preserving, and offers the possibility of direct amplification of few-cycle pulses.
