Abstract:
A laser diode device, including:lower and upper blocks of dielectric material, each said block defining a semi-cylindrical cavity; a bonding layer of molybdenum manganese lining each said cavity, each said layer being of macroscopic thickness; said upper block inverted relative to said lower block and mounted thereon to define therewith a cylindrical cavity; a cylindrical copper ring disposed within said cylindrical cavity and bonded to said bonding layers of said lower and upper blocks, said copper ring including a plurality of separate ring sectors with radial diode bar spaces between adjacent sectors, the copper of said ring being of a thickness substantially greater than the thickness of said bonding layers; and a laser diode bar disposed in each of said bar spaces in a circumferential array of said laser diode bars; said ring sectors and said laser diode bars together forming a series path for electric current around said copper ring to energize said laser diode bars.
