Online mRad divergence calculator, measure output beam diameter and then spot diameter at a distance, input numbers: https://www.laserworld.com/en/laserw...ivergence.html

Beam divergence calculator - you can clearly see the importance if the distance is increased: https://www.laserworld.com/en/laserw...alculator.html

If building a low divergence fat beam pointer, what diameter lens do you need for a given distance from your diode? Find the angle of radiation for the raw output of the diode and determine the size needed at a given FL: http://www.1728.org/angsize.htm

Laser diode self-mixing: Range-finding and sub-micron vibration measurement

A plain laser diode can easily measure sub-micron vibrations from centimeters away by self-mixing interferometry! I also show how this technique can be used for range-finding.
