Impulsive excitation of a solid by extreme contrast, high intensity femtosecond laser pulses Open
We present the ultra-fast dynamics of the interaction between a high-intensity extreme contrast (expected to be around 1e-18 at hundreds of picoseconds timescale) femtosecond laser and a solid. Simultaneous measurements of probe Doppler sp…

Spatial, Spectral and Temporal Response of High Intensity Laser Plasma Mirrors- Direct Observation of the Ponderomotive Push Open
Plasma-based optics have emerged as a powerful platform for manipulating and amplifying ultra-intense laser pulses. However, the inherently nonlinear and dynamic nature of plasma leads to significant spatial, spectral, and temporal modulat…

Capturing the three dimensional, nano-scale, pico-second dynamics of plasma mirrors with intense ultrashort laser wavefront measurement Open
We present a direct measurement of the nanoscale dynamics of plasma mirrors using wavefront measurement techniques. This two-dimensional measurement, performed via pump-probe diagnostics, enables the reconstruction of the three-dimensional…

Generation of mega-gauss axial and azimuthal magnetic fields in a solid plasma by ultrahigh intensity, circularly polarized femtosecond laser pulses Open
The interaction of intense linearly polarized (LP) femtosecond laser pulses with solids is known to generate azimuthal magnetic fields, while circularly polarized (CP) light has been shown to create axial fields. We demonstrate through exp…
