Subject: Green Laser Pointer beam profile 

This measurement was made with the Thorlabs DCC1545M-GL camera with an RG850 3mm long-pass filter over the CCD.

The beam radius (w) is 191 pixels, where the beam intensity = exp[-2 (x/w)^2 ]

The pixel size is 5.2um. Hence the beam size is 993.2um, which is basically near enough to 1mm radius.
