Abstract:

Extensive analytical studies of laser modes and optical resonators led to the formulation of a general theory and graphical treatment of optical resonators with focusing elements. This published work is now expanded to include cases involving nonparallel axes of symmetry. The optical resonator theory was experimentally applied to a triangular ring optical resonator. Beat frequencies between various modes were measured. The results were in agreement with the analytically predicted frequencies. A GaAs diode laser with an external ellipsoidal mirror was analyzed and experimentally studied. Reduction of spot size is treated and the apparatus to position the diode-mirror combination is described. Dual canted Fabry-Perot mode selector etalons were experimentally studied with a ruby laser. Beam-angle narrowing in two dimension is shown. The theory of frequency selectivity and angle narrowing is reviewed. Author
