    Abstract. Some applications of polymer films require the microstructuring of partly uneven substrates. This cannot be achieved by conventional photolithography, usually performed with ultraviolet short-pulse lasers (excimer, fourth harmonic Nd:YAG). When processing thermally sensitive or undoped...

    Abstract. Theoretical study of laser ablation is usually based on the assumption that the vapor is an ideal gas. Its flow is described by gas dynamics equations [1, 2]. The boundary conditions at vaporization front are derived from the solution of the Boltzmann equation that describes the vapor...

    Micro machining of a polyimide film with ultra-short pulsed laser was demonstrated. A through-hole with a diameter of less than 10 μm could be produced by optimizing the pulse duration, repetition rate, and number of shots. Thermal damage around the through-hole can be made negligibly small...

    The emission dynamics of polymer distributed feedback lasers have been studied following excitation by femtosecond laser pulses. The lasers were found to generate pulses as short as 800 fs. The dynamics were investigated as a function of pump power and excitation spot size. Simple rate equations...

    A fluence advantage was achieved in dry/damp laser cleaning by reduction of the laser beam dimensions. 0.1 μm Al2O3 particles were removed from glass slides using a KrF excimer laser (248 nm). As the width of the rectangular beam was reduced, a decrease in the threshold fluence required for...
