…(intensity profile). Beam Profile vs. Beam Propagation Beam profilers measure the spatial intensity distribution of a laser beam. However, no matter how accurately and diligently a profile is measured, this information does not predict the intensity distribution elsewhere along the beam path. If the…

LaserCam-HR II User Manual

LaserCam-HR II User Manual

…II beam diagnostics cameras use laser-grade
1/2-inch and 2/3-inch CCD sensors for detection and analysis of
laser beam profiles from ~150 micron to 4 mm in diameter (1/2-inch
camera) and ~150 micron to 6 mm in diameter (2/3-inch camera).
The 1/2-inch model is a 12-bit camera with…

…these reflected beams in a configuration called a Mach-Zehnder interferometer. The recombined
beam is then expanded and viewed using a CCD camera.
If the OPSL chip remains flat with no thermal lensing, then the image at the camera would be
uniform across its profile. Conversely, any…

…specification.
Beams with a very small divergence, i.e. with an almost constant beam diameter over a significant propagation
distance are generally called "collimated beams".
To measure divergence correctly with a camera based beam analyzer (profiler), a lens or confocal mirror…

flat-top profile, with intensity that rises quickly to a fixed
level and is then flat across the beam.
Laser profiles are normally Gaussian, with optics and
apertures used to transform this into a flat top. For lowerpower lasers, a camera or a scanning-slit profiler is used
