| Popis: |
The absolute flux of a femtosecond vacuum ultraviolet VUV photon source based on the high order harmonic generation of a femtosecond Ti sapphire laser and monochromatized with a grating monochromator is determined both on a shot to shot basis and averaged over seconds by a calibrated gas monitor detector. The average flux is compared with the average flux as determined with a calibrated GaAsP semiconductor photodiode. We found that the photodiode is a reliable and easy to use tool for estimating the order of magnitude of the average photon flux but that, due to saturation losses, it underestimates the average flux by up to amp; 8722;15 |
