Fast ignition in Inertial Confinement fusion (ICF) is an important technique to enhance the coupling efficiency of the laser to the core [1]. One of the primary challenges faced in fast ignition is the electron divergence, leading to reduced laser-core coupling [2]. A key solution to this problem is the generation of intense Megagauss magnetic fields to guide the ignition electrons, which...
Recently, orbital angular momentum (OAM) beams have demonstrated at relativistic intensities at several high-power laser facilities around the world using off-axis spiral phase mirrors. The additional angular momentum carried by OAM beams, even when linearly polarized, introduces a new control parameter in laser plasma interactions and has shown promise to introduce new and exciting phenomena...
Betatron x-rays from a laser wakefield accelerator provide a new avenue for high-resolution, high-throughput radiography of dense materials. Here, we demonstrate the optimization of betatron x-rays for high-throughput x-ray imaging of metal alloys at the laser repetition rate of 2.5 Hz. Using the Advanced Laser Light Source in Varennes, QC, we characterized the x-ray energy spectrum, spatial...
Cold plasma technology finds diverse applications spanning from microfabrication, medicine, agriculture, and surface decontamination. Precision required in these applications usually necessitate high control over the electric field of plasma sources, allowing for tailored targeting of specific chemical pathways. To determine the electric field, high-resolution detection techniques are...
