Ultrafast Nonlinear Optics High Harmonic Generation Project
Explore the project on high harmonic generation in ultrfast nonlinear optics, aiming for 5th harmonic generation using the Kansas Light Source laser. Learn about harmonic frequencies, design components like Barium Borate and Argon Gas, and achieve a 3rd harmonic light with 5% power conversion efficiency. Future work involves building, optimizing, and testing a 5th harmonic generator setup.

Ultrafast Nonlinear Optics: High Harmonic Generation Justus Kornkven Advisor: Dr. Vinod Kumarappan
Project Goals 5thHarmonic Generation using the Kansas Light Source (KLS) laser. What is Harmonic Generation? 5th Harmonic Frequency: 5? =? Fundamental Frequency: ? =? 1 5 ?1 ?2= ?1 ?2 For KLS: 790nm goes to 158nm
Design ? Barium Borate BBO ? ? ? 3? 5? ? + 3? 2? 2? Argon Gas ? BBO Calcite HWP BBO Chamber THG FHG Method References: Marcus Beutler, Masood Ghotbi, Franck Noack, 2011, Generation of Intense Sub-20-fs vacuum ultraviolet pulses compressed by material dispersion, Optics Letters, Vol. 36 Rimantas Budriunas, Collinear Setup For Two-Color High Harmonic Generation, Lund University
