Abstract:
1. A method of fabricating a reticle for a telescopic sight, the method comprising the steps of: directing ultrashort laser pulses toward a glass block; and forming a subsurface object within the glass block, the subsurface object having a plurality of intrinsic scattering layers; wherein the forming step includes selecting a polarization state of the ultrashort laser pulses to vary a polarization dependence of the subsurface object over the plurality of intrinsic scattering layers; and wherein the forming step includes writing a first intrinsic scattering layer of the plurality of intrinsic scattering layers within the glass block with the ultrashort laser pulses in a first polarization state, and writing a second intrinsic scattering layer of the plurality of intrinsic scattering layers within the glass block with the ultrashort laser pulses in a second polarization state.
