Time Frequency Analysis of Higher Harmonic Generation in a Three Color Laser Pulse
high harmonic generation is a useful tool for the generation of short, intense attosecond pulses. In order to simulate high harmonic generation, we performed a numerical solution to the time dependent Schrödinger equation. by considering dipole approximation, we predicted generation of a 53 attosecond pulse. In order to see the time and frequency of emission of attosecond pulse, we exploit...
متن کاملPhase Matched Third Harmonic Generation of a Gaussian Laser Pulse in High-Density Quantum Plasma
Third harmonic generation due to linearly polarized Gaussian laser pulse propagating through quantum plasma immersed in transverse wiggler magnetic field is studied using the quantum hydrodynamic (QHD)model. The effects associated with the Fermi pressure, the Bohm potential and the electron spin have been taken into account.Wiggler magnetic field plays both a dynamic role in producing the harmo...
متن کاملInterferometric Backward Third Harmonic Generation Microscopy for Axial Imaging with Accuracy Beyond the Diffraction Limit
A new nonlinear microscopy technique based on interference of backward-reflected third harmonic generation (I-THG) from multiple interfaces is presented. The technique is used to measure height variations or changes of a layer thickness with an accuracy of up to 5 nm. Height variations of a patterned glass surface and thickness variations of fibroblasts are visualized with the interferometric e...
متن کاملSimultaneous fs pulse spectral broadening and third harmonic generation in highly nonlinear fibre: experiments and simulations
Experiments and numerical simulations are used to study non-phasematched single-mode third harmonic generation occurring simultaneously with fs pulse spectral broadening in highly nonlinear fibre. Pump pulses around 100 fs at 1560 nm injected into sub-5 cm lengths of commerciallyavailable highly nonlinear fibre are observed to undergo spectral broadening spanning over 700 nm at the −30 dB level...
متن کاملContinuum generation of the third-harmonic pulse generated by an intense femtosecond IR laser pulse in air
The continuum generation by intense femtosecond IR laser pulses focused in air including the effect of thirdharmonic generation is investigated. We have used a theoretical model that includes the full spatio-temporal dynamics of both the fundamental and the third-harmonic pulses. Results of our numerical calculations show that a two-color filamentation effect occurs, in which the third-harmonic...
