laser spectroscopy
... The apparatus for the Doppler-free saturated absorption spectroscopy of rubidium is shown in Figure 6. The output beam from the laser is split into three beams, two less intense probe beams and a more intense pump beam, at the thick beamsplitter. The two probe beams pass through the rubidium cell fr ...

High Power Operation of a 17 GHz Photocathode RF Gun
... The goal of the 17 GHz photocathode experiment is to construct an ultra high-brightness source of electrons which can be used for free electron lasers or future linear colliders. The photocathode RF gun is a novel electron beam source intended to meet the requirements set by future high-energy linea ...

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.
