…of beam width is the width at which the beam intensity has fallen to 1/e² (13.5%) of its peak value. This is derived from the propagation of a Gaussian beam and is appropriate for lasers operating in the fundamental TEMoo mode or closely. In reality, many lasers exhibit a significant amount of beam…
