Light scattering described in the mode picture
... The description of the effect of a wave-front deformation by a single number such as the TIS or the scattering angle, above which the light is considered as being lost from the original mode, is a relatively poor one and might not be adequate for all applications. A more appropriate approach is to u ...

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.
