Microsoft Word - Understanding Laser Beam Parameters Leads to Better System Performance and Can Save Money Final.doc

…adjustment of the beam diameter does not affect the total power being delivered by a laser
beam, but does effect how the total power is concentrated. Controlling the power density or brightness of a laser beam
requires the control of both laser power and beam diameter.
The accurate…

…apply: First of all, the beam intensity is not
limited by the size of the pinhole or slit width. Secondly, the
signal-to-noise ratio is very high. Thirdly, resolution is not limited
by the size of the aperture allowing beams of a few microns in
diameter to be measured with a…
