1. A laser gain material module, comprising:
a lasing portion; and
a perimetral portion formed in a predetermined shape to substantially prevent any spontaneously emitted photons created in the lasing portion and entering the perimetral portion from returning to the lasing portion, wherein the laser gain module forms substantially one of a disk and a slab, and wherein an outer perimetral edge of the perimetral portion opposite to the lasing portion is one of open to open space to allow any spontaneously emitted photons to pass from the perimetral portion into the open space and has an ASE cladding or an absorption coating to absorb any spontaneously emitted photons.
