Efficient keV x‐ray emission from plasmas generated with 4 ps KrF excimer laser pulses

A high x‐ray conversion efficiency is observed from plasmas produced with 4 ps pulses at 249 nm using commercial KrF lasers. Copper plasmas convert 11% of laser energy into hν∼1.2 keV photons, carbon plasmas 6.8% into ‘‘water window’’ photons (0.28 keV<hν<0.53 keV) and aluminum plasmas 0.4% into hν∼1.6 keV photons.
