In recent years, the need for an easy control of laser beam quality has led many researchers to look for its best definition and for its characterization. In this paper we describe the possibility to control the stability of the laser beam quality by monitoring, in real time, the fluctuations of the M2 factor, defined by Siegman, together with other parameters like the waist and the far field divergence and, in the case of pulsed lasers, the pulse length and the peak power. In spite of its simplicity and low cost, our apparatus can easily work from cw to femtosecond regime.

Abstract
In recent years, the need for an easy control of laser beam quality has led many researchers to look for its best definition and for its characterization. In this paper we describe the possibility to control the stability of the laser beam quality by monitoring, in real time, the fluctuations of the M2 factor, defined by Siegman, together with other parameters like the waist and the far field divergence and, in the case of pulsed lasers, the pulse length and the peak power. In spite of its simplicity and low cost, our apparatus can easily work from cw to femtosecond regime.File in questo prodotto:
