ABSTRACT:
A light stop having at least one appropriately laser textured surface assures the absorption of energy including laser emissions that impinge on the at least one surface to thereby inhibit reflected energy therefrom. Optionally, an improved emitter of energy is created by at least one appropriately laser textured surface having an increased surface area of emission to increase the emissive power of the surface to thereby provide improved conductive and radiative cooling. An improved absorber and emitter is fabricated by providing front side and backside textured surfaces. All these capabilities are provided in a variety of structural configurations.
