Abstract:
An investigation was made of the absorption spectrum of KrF2 in the range 115–190 nm. A structure-free absorption band with a maximum at 162 nmand a half-width of 16 nm was observed. The absorption of light in this band resulted in photodissociation of KrF2 producing excited KrF. Vacuum ultraviolet radiation generated by a high-current discharge was used to excite a KrF2–Xe–N2–Ar gas mixture. This resulted in lasing due to the B(v' = 0)–X(v'' = 3) transition in the XeF excimer (λ = 353 nm).
