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.
... Experimental laser systems benefit from the use of multiple laser beam profilers to characterize the pump beam, the output beam, and the beam shape at intermediate locations in the ... Changes in the pump laser beam profile indicate the health of the pump laser, which laser modes are excited in the gain crystal, and also determine whether the laser is warmed up by locating the ... The output beam profile is often a strong function of pump power due to thermo-optical effects in the gain medium ...
Famous quotes containing the word beam:
“Why beholdest thou the mote that is in thy brothers eye, but considerest not the beam that is in thine own eye?”
—Bible: New Testament Jesus, in Matthew, 7:3.
