Abstract:
An optical amplifier comprising:an elongated slab of a solid state lasing material having a predetermined cross-section defining opposing end faces and a plurality of lateral faces therebetween, a longitudinal axis defined between said opposing end forces generally parallel to said lateral faces;means for enabling pumped light to be directed along an axis generally parallel to said longitudinal axis, said enabling means including a first footprint formed on said slab adjacent one of said opposing end faces, said footprint including a coating disposed on one of said end faces and a portion of lateral faces adjacent said one end faces, said one of said end faces configured at an angle relative to said longitudinal axis, said footprint enabling pump beams directed at an angle generally perpendicular to the surface of said lateral surface to be directed along said longitudinal axis; andone or more sources of pump beams.
