• crosstalk [17]. The laser beam deflection system in our AFM employs a laser wavelength of 1310 nm, which is well below the bandgap of our sample; therefore, the parasitic laser absorption, which may interfere with the KPFM measurement, is reduced to negligible levels [13].

• selectivity based on surface plasmon resonance [15]. An increase of the laser-absorption efficiency can be expected in plasmonic nanoparticles, which results in the efficient generation of highly ionized charge states [13][14]. It is expected that this characteristic interaction between intense femtosecond

In practical applications for X-ray diffraction [7] and X-ray absorption fine structure (XAFS) measurements [8][9], or further nonlinear X-ray processes, a high flux of X-ray pulses is indispensable. X-ray intensity enhancements can be expected through an effective increase of the laser

• ultraviolet (UV) laser radiation is in the range of tens of nanometers for many materials [17]. The laser pulse energy is deposited in a very thin layer beneath the surface of the laser target, which has a thickness of the order of magnitude of the laser absorption length. If the irradiated film thickness is
