We show how tailored few-cycle lightwaves with near relativistic intensity (∼1018W/cm2) can be used to control the attosecond electron dynamics of plasma mirrors and to produce beam manifolds of fully synchronized attosecond EUV light pulses.
We present pump-probe measurements that reveal significant changes in the group delay dispersion of a femtosecond laser pulse being controlled by the relative delay between two pulses. We suggest applications for this time-domain shaping approach.
Linear and non-linear Fano interactions in a hybrid system consisting of surface plasmonic resonance and alkali vapor are presented. Using a pump probe apparatus, Doppler free lineshape and all optical modulation is experimentally demonstrated.
We study the dynamics of the plasma generated with 800nm filaments of 60fs in a pump-probe system in nitrogen cell. We see the effect of molecular revival and plasma dynamics on beam profile and spectrum.
We report the second harmonic generation of a near-infrared pulse in a Gallium Phosphide crystal through the Pockels effect induced by an intense terahertz pulse. This demonstrates cascading second-order nonlinear phenomena in the terahertz range.
We present the first compact, all-fiber probe laser system for mid-IR photothermal spectroscopy. Images of the vibrational CH bands of a liquid crystal sample with high contrast are demonstrated.
Time-resolved absorption of a 500-fs laser pulse by fused silica is measured. The results evidence a strong contribution of linear absorption for high pump fluence, during the entire pulse length.
A fast all fiber based setup for stimulated Raman spectroscopy with a rapidly wavelength swept cw-laser is presented. It enables flexible acquisition of broadband (750 cm−1 to 3150 cm−1) spectra with high resolution (0.5 cm−1).
The free-carrier cross-section of Si-QD is decreased from 5.5×10−17 to 9×10−18 cm2 with shortened lifetime from 10 to 0.48 µs when shrinking Si-QD size from 4.3 to 1.7 nm due to the quantum confinement effect.
We visualize formation, propagation and collapse of laser-driven plasma bubbles using a single-shot frequency domain streak camera, thereby identifying bubble dynamics that optimize electron injection and acceleration.
Time- and angle-resolved photoemission spectroscopy directly enables observation of electron dynamics in condensed matter. Using EUV high harmonic probe extends the observation window in energy and momentum. Tunable mid-infrared pumping allows control of excitation mechanisms.
