Paper Abstract

General conditions for generating high gain by expansion cooling will be discussed. Theoretical and experimental studies of the carbon fibre approach show good agreement. The development of scaling laws for this simple system allows optimisation and flexibility to be identified in the operating conditions. Seeding and coating the fibre with appropriate elements introduces further flexibility by additional radiation cooling. Fibre doping with elements from nitrogen to neon extends laser action from 182Å to 61Å. Shorter wavelength operation at 39Å may be generated from aluminium based targets.
