Abstract:
1. A blue extended super continuum light source arranged to provide a generated spectrum having an intensity I(λ) as a function of wavelength λ and having a blue part relative to a pump wavelength λ pump comprising wavelengths from λ pump −λ 1 to λ pump −λ 2 , wherein λ pump −λ 1 <λ pump /2, said light source comprising: a) a micro structured optical fiber adapted to transmit radiation at λ b) a pump source pumping said microstructured fiber with pump pulses at said pump wavelength with a duration, full width half maximum, of T wherein said pump source and microstructured optical fiber is arranged such that a part of each of said pump pulses pumped into said fiber breaks into trains of Tera Hertz repetition rate pulses, the generated spectrum extends to the infra red absorption band edge stabilization point, and I(λ)>−5 dBm/nm for a range of wavelengths from λ
