Abstract:
Pulsed desorption of organic conducting polymer by XUV-photons, formed by a thin capillary collimator, has been investigated. Short-wavelength radiation has been resulted from a metal target irradiated by a sharply focused Ti:Sa laser beam (0.8 μm, 40 fs, 3 mJ∕pulse) and has been filtered by Mylar-gold substrate. Single shot and 1-kHz pulses regimes of driving femtosecond laser have been compared using a time-of-flight mass spectrometer. A stepwise function of photoion signal vs laser pulse energy has been observed.
