100 fs light pulses of around 800 nm were generated by a Ti: Sapphire oscillator, then amplified to approximately 30 GW peak power using a chirped pulse amplification system that included regenerative and multi-pass amplifiers. High power pulses were then used to strike water, glass, and a Kerr Cell. Supercontinuum generation was observed as a result of striking the water and glass. Moreover, using water produced a stable source of white light.
This experiment demonstrates some of the foundational elements of the early days of optical chirped pulse amplification leading up to the 2018 Nobel Prize in Physics and looking forward to vacuum breaking laser intensities. The experimental set-up and principles of operation will be discussed.
