The industrial development is coming with other and other requests for a new materials. The way is same in optic and optoelectronic (interdisciplinary flied dealing with transfer and processing of optic signal) fields and in other related ones. The special glasses can be divided in following base group, as the schema of single description of researching problems shows:

Halide glasses

often toxic, volatilize by preparation, sensitive to humidity, radiation transmit in UV/VIS-MIR areas

Chalcogenide glasses

preparation must be done at inert atmosphere or vacuum (other way its react with an air), often content with toxic compound (As), radiation transmit in VIS/NIR-MIR areas

Heavy metal oxide (HMO) glasses

problems with the purity products, big disadvantage is containing OH- groups inductive of huge absorption at wave length 2.9 mm; radiation transmit in VIS-NIR/MIR areasMixed glassesfor example halide-oxygen, chalcigenide-halide, …

Application of special glasses:

Application of passive optical materials:

transfer of optical signals (communication, remote spectroscopy, ...)

energy transfer of giant-pulse laser (surgery, mechanical engineering, ...)

image transfer through fiber bundle

various fiber sensors

lenses and instrumental windows
Application of active optical materials:

fiber source of laser

amplifier of optical signals

various sensors
Application of nonlinear optical materials:

(used the non-linearity of mass response by interaction with intensive rays)

generation of secondary harmonic frequencies

polyphoton absorption

self-focusing instrument
