Claims43
A device for optical switching, frequency conversion, and protection of sensory organs and optical and electronic sensors which comprises at least one layer comprising a polymerized transition metal poly-yne interposed in the path of a laser light so as to have a nonlinear optical effect thereupon.
A device for optical switching, frequency conversion, and protection of sensory organs and optical and electronic sensors which comprises a dry, free-standing cast film of a power-limiting, polymerized transition metal poly-yne having repeating units of the formula:
- ##STR10## interposed in the path of a laser light so as to have a nonlinear optical effect thereupon.
A device for optical switching, frequency conversion, and protection of sensory organs and sensors from high power laser beams comprising at least one power-limiting organic polymeric layer which comprises an organometallic polymer having at least one of the following repeating units:
- ##STR11## wherein M is a transition metal;
- L is a ligand;
- R is an organic substituent;
- m is a whole number from 0 to 4, inclusive;
- and n is a whole number from 1 to about 200, interposed in the path of a laser light so as to have a nonlinear optical effect thereupon.
A method of optical switching, frequency conversion, and power limiting of a high power laser beam which comprises interposing in the path of said laser beam at least one layer comprising a polymerized transition metal poly-yne.
