Nonlinear Optical Absorption

Nonlinear optical absorption for interband-resonant light by intraband-resonant light in n-doped quantum well structure is experimentally demonstrated. The nonlinearity is caused by the third-order interaction between interband- and intraband-resonant lights through a guided-wave structure. The amount of absorption for interband-resonant light is increased by 60% with the incidence of intraband-resonant light of 100–200 kW/cm2.

SUMMARYThus, in the present paper, we reported about several processes of nonlinear absorption and transmission in dye-doped NLC: nonlinear absorption due to light induced reorientation of NLC doped by highly dichroic dyes; nonlinear transmission due to nonlinear birefringence, and self-extinguishing of the beam due to”critical opalescence,” critically enhanced light scattering at the pre-transition region of nematic-isotropic phase transition. All these processes have large application potential for laser beam control and characterization techniques.
