The present invention is directed to a laser communication transmitter and receiver for wireless optical communication. The method is disclosed for filter cake formation, fluid loss control, drilling, hydraulic fracturing and fiber assisted transport, where removal of the polyol at the end of treatment or after treatment is desired. The stripping pin housing includes a number of radially extending grooves in its axial surface. The DUV laser anneal step of the present invention likely removes the weakly bonded C from the film, thus improving leakage current. The plurality of equations are solved to obtain estimated values of the unknown participating practitioner entity outcome indices and estimated values of the unknown participating practitioner entity type indices.
