#192: Lasers 101, Particle Physics & Nonlinear Optics ft. G. Ravindra Kumar
How do lasers work, and how can extreme laser light be used to study matter at the most fundamental level? In Know Time Episode 192, physicist G. Ravindra Kumar takes us from the basics of lasers to the cutting edge of nonlinear optics, intense light-matter interactions and particle physics. We explore how lasers generate and control light, what happens when extremely intense laser pulses interact with matter, and how these interactions can create extraordinary conditions that help scientists investigate fundamental physics. The conversation also explores nonlinear optics, high-intensity lasers, plasma physics, particle acceleration and laboratory experiments that recreate extreme, star-like conditions. If you're interested in lasers, quantum physics, particle physics, optics, plasma physics and how extreme light can reveal the fundamental nature of matter, this episode offers an accessible introduction to the science behind these experiments. ️ Guest: G.
