Mechanically hard and broadband gradient refractive index antireflection coating was developed. It has a high damage threshold of >=6 J/cm2 at 355 nm and 12–13 J/cm2 in the visible to near-infrared region. It will be applicable to high power pulsed lasers as well as to industrial uses.

    The mechanisms of SiO ablation have been investigated at laser wavelengths in the infrared, at 10.53 μm, and in the ultraviolet at 248 nm. The energy content of the SiO molecule in the plume and the occurrence of phase transformations in the target, are studied as a function of wavelength and...

    We demonstrate continuum generation with pulses from the long femtosecond up to the picosecond regime. To understand the mechanism involved in this process we study the influence of the spectral width and the chirp of the pump pulses. We further investigate the threshold for stable continuum...

    We report on comparative study of magnetic properties of Pt/Co/Pt trilayers after irradiation with different light sources. Ultrathin Pt/Co/Pt films were deposited by molecular beam epitaxy technique on sapphire (0001) substrates. Pt buffers were grown at room temperature (RT) and at 750°C...

    Fourier-transform-limited pulses of programmable length and shape have been generated in the range λ=720–825 nm from the continuous-wave output of a Ti3+-doped sapphire (Ti:Sa) ring laser using a pulsed acousto-optic modulator (AOM). The minimal rise time of the pulses amounts to 10 ns...

    Investigations have been performed on the physical mechanisms of picosecond laser ablation of silicon carbide at 355 and 1064 nm, which have not been well understood yet. The study shows that the low-fluence ablation rates are close for 355 and 1064 nm, and the dominant material removal...
