Abstract

We use time-of-flight (TOP) mass spectrometry to study the interaction of free C60 molecules with ultrashort high-power Ti:sapphire laser pulses. Figure 1 shows the intensity dependence of the ion yield for singly and doubly ionized C60 and singly ionized fullcrenc fragments (C60.20, n < 10) after excitation with the doubled (2ω)) and the fundamental (ω) Iaser frequency. From calibration measurements, we estimate the maximum intensities to be approximately 5 × 1013 W/cm2.
