From Nonlinear Optics to High-Intensity Laser Physics

Director’s Special Colloquium

Abstract: The laser increased the intensity of light that can be generated by orders of magnitude and thus brought about nonlinear optical interactions with matter. Chirped pulse amplification (CPA) changed the intensity level by a few more orders of magnitude and helped usher in a new type of laser-matter interaction known as high-intensity laser physics.

In this talk, I will discuss the differences between nonlinear optics and high-intensity laser physics. The development of CPA and why short, intense laser pulses can cut transparent material will also be included. I will also discuss future applications.
