This lecture is part of the 2019 Loeb Lectures in Physics, delivered by Donna Strickland, Professor, Department of Physics & Astronomy, University of Waterloo; Nobel Laureate, Physics 2018

There are a host of nonlinear optical experiments requiring two synchronized pulses having different frequencies. Professor Donna Strickland will discuss how University of Waterloo has developed two-color Chirped Pulse Amplification (CPA) laser systems to carry out some of these nonlinear optics experiments. Currently, they are studying Multi-frequency Raman generation (MRG) with the aim of produce ultrashort pulses using a two-colour, Ti:sapphire system. A second two-color system based on fiber CPA is used to generate long wavelength mid-infrared radiation through difference frequency mixing. In the future, the two-color fiber system should also provide a high average power source of single-femtosecond pulses using MRG.
