In traditional nonlinear optics, the process of THG is known to vanish identically for an isotropic medium for a circularly polarized fundamental laser beam [14]. Let us recall why traditional models [15] predict the vanishing of THG under excitati ...

Laser beam profiler
A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path. Since there are many types of lasers — ultraviolet, visible, infrared, continuous wave, pulsed, high-power, low-power — there is an assortment of instrumentation for measuring laser beam profiles. No single laser beam profiler can handle every power level, pulse duration, repetition rate, wavelength, and beam size.
