Paper Abstract

A new laser processing technique was proposed and demonstrated for producing high-temperature sol-gel coatings on substrates like ZnSe or chalcogenide infrared fibers which cannot be exposed to relatively high temperatures involved in most sol- gel processes. Our approach is similar to the 'indirect writing' technique except that an air gap is inserted between the sol-gel coating and the light absorber so as not to affect the optical coating. Our processing technique integrates optical sol-gel coatings having tailored properties of porosity, surface area, and surface affinity with substrate materials used for integrated and fiber optic infrared technologies such as optical sensors.
