Abstract

This paper considers the transverse optical properties of an absorbing ring when it is lighted by a symmetrical Laguerre–Gauss beam TEM p 0 . It is demonstrated that the insertion of an opaque ring having adequate size inside a diaphragmed laser cavity is able to improve greatly (rate of about 100%) the discrimination between the TEM 00 and the TEM 10 modes, while keeping the diffraction losses unchanged or even decreased.
