We decribe the behaviour of an annular RF-excited CO2 laser, operated with a Talbot cavity in order to reduce the number of oscillating azimuthal modes. The beam quality is enhanced by means of a phase filter outside the cavity.

Abstract
We decribe the behaviour of an annular RF-excited CO2 laser, operated with a Talbot cavity in order to reduce the number of oscillating azimuthal modes. The beam quality is enhanced by means of a phase filter outside the cavity.File in questo prodotto:
