ABSTRACT:
A cylindrical laser rod has a cylindrical sleeve surrounding it, the cylindrical sleeve having a reflective coating applied to its periphery with one or more transparent flats or slits being positioned in an equiangular fashion about the sleeve. At each slit, a focus lens and a retro-reflecting lens is mounted thereto, with the focal lens being aligned in an off axis orientation such that a linear laser diode array can be aligned with the focus lens and its beam directed in a off axis path through the laser rod for reflection a plurality of times through the sleeve and rod, the beams being returned along its reflecting path by the retro-reflector to maximize the coupling between each linear laser diode array and the laser rod.
