For one and a half decade, software for interferometric fringe evaluation has been developed and used at Graz University of Technology. Within the framework of an awarded grant, these software packages on interferometric fringe evaluation were subsum

A styrene copolymer of 4-vinylbenzyl thiocyanate (PST-co-VBT) was employed as recording material for optical interference patterns with periods Λ < 1 μm. Using lower intensity laser irradiation (4 mJ cm-2, λ = 266 nm), refractive index gratings we

Relative intensity measurements of Al I and Al II spectral lines in the visible and ultraviolet spectral ranges are performed using a capacitively coupled high frequency double hollow electrode discharge. Branching ratios and intensity ratios within

We report on strong amplified spontaneous emission observed both in solution and in neat films of a conjugated polymer. The emission characteristics of a three-layer polymer waveguide are presented. The intense, highly directional, completely linear

We applied the recently developed method for determination of the power law in the degenerate four-wave mixing process in order to use a Boltzmann plot for determination of the rotational temperature of nitric oxide molecules generated in an oxyacety

A new experimental technique suitable for real-time measurements has been developed which permits the determination of the spatial distribution of the electron density of a plasma with a time resolution commensurate with the 6 ns duration of a single

A fast-rise-time capillary discharge was designed and investigated as a possible source of amplified spontaneous emission in the extreme ultraviolet spectral range. The capillaries were made of Li 2 CO 3 or SiO 2 with radii in the range 0.25-1 mm and

Compared to the neon atom, where levels belonging to different level groups nl or nl' are well separated from each other, most of the level groups in the neutral xenon atom overlap. We present investigations of the groups 7p, 6p' and 6d and discuss t

A time‐dependent, zero‐dimensional collisional‐radiative model has been developed to study capillary discharge plasmas in view of possibilities for obtaining population inversion leading to laser action in the extreme ultraviolet and soft x‐r

Absolute transition probabilities of 52 transitions of Co II with the upper levels belonging to the multiplets z 5 F o , z 5 G o and z 5 D o have been obtained by determining branching ratios and by combining these with lifetime values measured by ot
