We summarize in this work the salient points of the studies carried out at the National Institute of Optics (INO) in Florence in the vast field of coherent laser arrays. The research began in the early 90s under the push of Tito Arecchi with the stud

The transient dynamics of a Q-switched CO 2 laser is modelled quantitatively on the base of the four level model, a five dimensional nonlinear system of ordinary differential equations. Using the multiple shooting technique, internal parameters of th

Recently (Ciofini et al 2003 J. Opt. A: Pure Appl. Opt. 5 186–91) we introduced the use of very low-frequency diffraction gratings to extract good-quality, low-power copies of a high-power laser beam. We proved that beam propagation parameters are

We present a characterization of two narrow band filters commonly used in Infrared Astronomy. Our study mainly quantifies the effect of temperature and tilt angle on the central wavelength and width of the transmission bands of such filters. This all

We characterize the polarization properties of the lowest order transverse patterns in a CO2 Fabry-Perot laser designed to minimize anisotropies in both the loss and detuning for different states of polarization. Emission with an annular intensity pa

Three rate equations describing the single-mode CO/sub 2/ laser dynamics are derived by applying the theory of linear filters to an improved four-level model. The model is studied in the case of periodic modulations of the losses and compared with th

The validity of the four-level model is controlled in an experiment with a ${\mathrm{CO}}_{2}$ laser with electronic feedback. A global application of center manifold theory allows one to reduce the number of varieties from six to four. Qualitative d
