H01S3/2256 - CPC Classification

Classification description:

Lasers, i.e. devices using stimulated emission of electromagnetic radiation in the infrared, visible or ultraviolet wave range characterised by the material used as the active medium; Gases the active gas being polyatomic, i.e. containing more than one atom comprising an excimer or exciplex KrF, i.e. krypton fluoride is comprised for lasing around 248 nm
