Abstract
Laser arrangements are disclosed wherein a plurality of individual laser beams at slightly different wavelengths are generated in respective capillary bore waveguides in a common body of dielectric material. The generated laser beams are caused to converge upon a preselected intersection point, either by constructing the bore waveguides with converging longitudinal axes or by deflecting the generated laser beams into the desired converging paths by means of an optical prism. A diffraction grating is positioned at the laser beam intersection point to combine the respective laser beams emitted from the bore waveguides into a composite beam along a coincident path.
