Efficient generation of high-order harmonics in gases

A harmonic is a wave with a frequency that is a positive integer multiple of the fundamental frequency, the frequency of the original periodic signal, such as a sinusoidal wave. The original signal is also called the 1st harmonic, the other harmonics are known as higher harmonics. As all harmonics are periodic at the fundamental frequency, the sum of harmonics is also periodic at that frequenc… WebNov 30, 2024 · High-order harmonic generation Multiphoton or tunneling ionization & excitation Strong electromagnetic field effects Atomic, Molecular & Optical Authors & Affiliations Jingguang Liang 1,2, Yu Hang Lai 1,2,*, Wufeng Fu 1,2, Yuwei Shan 1,2, Weili Yu 1,2,†, and Chunlei Guo 3,‡ how much money does an atm make
