We study and describe the reshaping of ultrashort and broadband mid-IR optical pulses in an ambient atmosphere. While all pulse propagation undergoes dispersion and absorption, which causes pulse reshaping, the effects are strongly pronounced for bro

We will discuss a carrier-to-envelope phase-controlled high brightness source of light covering 7 optical octaves. The spectral brightness up to 5 orders of magnitude higher than the brightest synchrotron and ranges from 340 nm to 40,000 nm.

B a G a 2 G e S e 6 (BGGSe) is a newly developed nonlinear material that is attractive for ultrabroad frequency mixing and ultrashort pulse generation due to its comparably low dispersion and high damage threshold. A numerical study shows the materia
