How hot can lasers get
WebA laser’s beam diameter characterizes the transverse extension of the beam, or its physical size perpendicular to the direction of propagation. It is often defined at the 1/e 2 width, which is bounded by the points where the beam’s intensity reaches 1/e 2 (≈ 13.5%) of its maximum value. At the 1/e 2 point, the electric field strength ...
