We present measurements of the spatiotemporal evolution of a hot-dense plasma generated by the interaction of an intense 25 fs laser pulse with a solid target. using pump-probe two-dimensional (2D) Doppler spectrometry. Measuring the time-dependent Doppler shifts at different positions across the probe beam. we achieve velocity mapping at hundreds of femtoseconds time resolution simul... https://jalyttlers.shop/product-category/toddler/
