Hard x rays are generated in laminar helium flow in atmosphere (without a vacuum vessel) through the interaction of tightly focused 35 fs laser pulses of varying energy with a Cu target. The energy conversion efficiency from laser to x rays is measured to be 5.4×10-6, giving a flux of 5.9×109 photons/s into sr from a source measuring approximately 9×12 μm2 in size (vertical×horizontal). Results are compared to those measured in vacuum and in static helium environments.
