Abstract
Few-cycle high peak power mid-IR sources are required for strong field applications, such as driving HHG in the keV range [1] and high efficiency THz generation [2]. In order to expose target to a peak field without causing excessive ionization, ultrashort pulses consisting of a few-cycles are needed. Parametric sources based on KTA crystals have been successfully used for the generation of multi-mJ pulses in the 3–4 µm range [3], however, the duration is typically limited to sub-100 fs duration due to phase matching bandwidth limitations. A robust and popular scheme for the generation of few-cycle pulses is via post-compression in a hollow core fiber (HCF) filled with noble gas [4] that yields uniform pulse compression across the beam and the perfect beam profile at the output due to spatial filtering effects.
