Sample Problems for Final
... Two narrow slits are separated by 10 microns. Light that passes through the slits illuminates a screen 1 meter away. Two separate colors of light, of approximately equal intensity, are incident on the slit: yellow light of wavelength 480 nm and red light of wavelength 640 nm. The central (m=0) maxim ...

Laser Beam Profile, Spot size and Beam Divergence
... The laser that we are working with is a rectangular one. So, any measurement done should has two primary orientation taken into consideration and the results should be given for both the orientations separately. The setup is very simple. We have a laser and a detector(for measuring the intensity) se ...

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.
