Abstract
A transversely-excited waveguide laser made up from the two blocks of electrically-insulating material. One block (1) has three parallel slots (3, 4 and 5) formed in one face, while the other block (2) forms a cover which may be secured to the first block to close the slots. The two outermost slots (4 and 5) each contain a layer (7) of electrically-conductive material to which an electrical conductor (8) is attached to form an electrode, while the dimensions of the center slot (3) are such as to enable it to form a laser cavity which will support waveguide laser action.
