HP-4-27-1 / Toward 100 W Average Power Few-Cycle Optical Parametric Amplifiers in the Mid-Infrared

We report on nonlinear refraction and absorption properties of commercially available oxide nonlinear optical crystals employed in ultrafast, GW optical parametric chirped pulse amplifiers (OPCPA’s) in the 3-5 µm part of the mid-infrared spectral range and discuss implications on average power scaling to the 100-W level. We demonstrate a 100-kHz OPCPA delivering 66 W in two optically synchronized beams at 1.5 and 3.2 µm. After chirp compensation, multi-GW peak power is achieved for both beams at a total average power of 55 W.
HP-4-27-2 / Phase-Matching Schemes for Back-Conversion Suppression in Nonlinear Wave Mixing: Towards Ultra-High Efficiency and Ultra-Broad Bandwidth
* Jeffrey Moses, Cornell University, United States
By suppressing the conversion-back-conversion cycles typical of optical parametric processes through novel phase-matching schemes, octave-spanning frequency conversion and highly efficient parametric amplification can be achieved. Several recent developments will be reviewed.

We show how gas-filled hollow-core fibers represent a unique platform to explore exotic nonlinear phenomena. We review our recent results including extreme pulse compression, terahertz and supercontinuum generation.
