We present a generalized perturbative analytical formalism for evaluation and optimization of the chromatic dispersion of complex ultrafast optical systems. Notably, we identify polynomial and recursive relations associated with the chromatic dispers

Publikováno v: Frontiers in Optics + Laser Science 2022 (FIO, LS).

The advent of intense coherent XUV sources opens up a novel regime of extreme nonlinear light-mater interactions. We theoretically identify attosecond resonant dynamics in high harmonic generation driven by XUV pulses, leading to efficient X-ray emis

High Performance Compression of 515 nm Laser Pulses at kHz-MHz Repetition Rates for Ultrabright EUV High Harmonic Generation

Autor: Siyang Wang, Jieyu Yan, Will Brunner, Dimitar Popmintchev, Tenio Popmintchev

Publikováno v: Optica High-brightness Sources and Light-driven Interactions Congress 2022.

We demonstrate a single-stage multi-plate compression of 515 nm second harmonic pulses of Yb:KGW laser amplifier from 180 fs to 40 fs, ideal for efficient EUV high-harmonic generation using 0.1-1 MHz visible driving lasers.

Publikováno v: Optica High-brightness Sources and Light-driven Interactions Congress 2022.

We demonstrate a dual-optic imaging-spectrometer for high harmonic generation sources, ideal for coherent diffractive imaging in a tunable monochromatic mode. Our optimization combines record-high efficiency, high spectral resolution, low aberrations

High-harmonic generation is a universal response of matter to strong femtosecond laser fields, coherently upconverting light to much shorter wavelengths. Optimizing the conversion of laser light into soft x-rays typically demands a trade-off between
