Abstract

I calculate and compare the effective reflectivities of the first three Laguerre–Gauss modes incident on an asymmetric Michelson mirror (MM) using a power ratio. It is shown that the oscillation of a laser, made with a MM in a three-mirror configuration, can be switched from one transverse mode to another simply by controlling the phase delay between the two MM arms.
