For the first time, selective sintering of amorphous PtCuNiP powder with a pulsed Nd:YAG laser has been studied. Upon pulsed interaction, the grains melt only superficially to build necks between the grains. Depending on the laser parameters, the sin

Evanescently coupled fiber laser arrays are investigated as a powerful and compact all-solid-state source of coherent radiation for high-power applications. The micro-structured multiple-core design provides a novel power scaling technique and overco

The concept of the Iwasawa decomposition [1] of ABCD ray-matrices is used for a systematic calculation of field distributions appearing in spherical optical systems. Examples of optimization for applications are calculated.

Neodymium doped SiO 2 –Al 2 O 3 samples have been produced by the sol–gel method and characterized by refraction index and fluorescence measurements. TiO 2 co-doping has been used to control the refraction index n up to a concentration of TiO 2 :

We report on an adaptive mirror system that allows generating thermo-optically controlled wavefront corrections. The influence of the wavefront is based on the thermal dependence of the refractive index in a thin active layer. The thermal pattern in

Diamond-like carbon (DLC) coatings were deposited on Si substrates using a hot filament diode discharge and they were irradiated with ultrashort laser pulses (800 nm, 150 fs, 2 ). The laser-treated films were examined using optical microscopy, Raman

The response of cemented tungsten carbide and of titanium carbonitride was investigated with respect to damage and ablation properties, under interaction with ultrashort laser pulses. These carbide materials present high microhardness and are of sign
