The International Conference on Ultrafast Phenomena (UP) 2022.
We have measured strong-field ionization yield versus laser intensity for various noble gases (Ar, Kr, Xe) and light polarizations from ultraviolet to near-infrared (267-800 nm), from multiphoton to tunneling regimes using cross-polarized temporal in

We report supercontinuum generation in a Te crystal pumped by picosecond CO2 laser pulses at intensities up to 20 GW/cm2. The effective nonlinear refractive index of Te is estimated to be 30x that of GaAs.

We report efficient second harmonic generation of picosecond CO2 laser pulses at intensities up to 50 GW/cm2 in GaSe, AgGaSe2, CdGeAs2, and Te. External energy conversion efficiency can reach 20% in AgGaSe2.

In situ generation of a high-energy, high-current, spin-polarized electron beam is an outstanding scientific challenge to the development of plasma-based accelerators for high-energy colliders. In this Letter, we show how such a spin-polarized relati

We measure nonlinear absorption in semiconductors using nanosecond and picosecond CO2 laser pulses. Absorption strength scales inversely with band gap energy. Effective absorption coefficients in n-Ge are unchanged over intensities from 0.1-2 GW/cm2.
