WebFeb 28, 2024 · The emitted light propagates similarly to a Gaussian beam since the guided fiber mode that carried the light has near-Gaussian characteristics. The divergence angle of a Gaussian beam can differ substantially from the angle calculated by assuming the light behaves as rays. Using the ray model, the divergence angle would equal sin-1 (NA ... WebOct 13, 2015 · $\begingroup$ The spot size of the beam is an inherent property of a Gaussian beam, and doesn't indicate that the beam has to focus coming out of the laser cavity if a lens is not present. The spot size itself for a Gaussian beam is directly related to its divergence angle. In some cases, the location of the minimum spot size can be … lines and angle mcq
