For the micromachining of temperature-sensitive and brittle-rigid components ultra short pulsed lasers are being used more and more. Due to the short pulse durations in the femto- and pico second range such systems with only a few Watt of average pow

Generating microstructures using ultra-short laser pulses reducing the thermal influence to the work piece is a rapidly growing technology field. The physical connections for material laser interactions with short laser pulses are often too complex f

Die Verwendung von Laserstrahlung zur Reinigung kunsthistorischer Objekte etabliert sich in den letzten Jahren zunehmend. Ein besonders verbreitetes und schwieriges Problem sind dabei Farbfassungen. Sie reagieren sehr empfindlich auf Laserstrahlung.

The UV wavelength at 248 nm of an excimer laser was used for basic investigations in cleaning of various encrusted sandstones as well as corroded medieval glass. Due to the combination of UV wavelength and short pulse duration (20–40 ns), this lase

To cover the whole range of applications in laser cleaning of artworks, it is well known that specific wavelengths are necessary for the individual conservation problem. Recently, there is a new generation of Nd:YAG-lasers available offering frequenc

The possibility to use laser radiation to clean historical objects has been established for several years. A complex case and widely met problem are polychromes. They react (chemically as also physically) very sensitively towards laser radiation. In

The self-limiting effect during laser cleaning only occurs in a limited amount of specific applications in restoration (e.g. removal of black crust from white marble). In all the other cases, a control of the removal process will be necessary either

Based on two independent feasibility studies in Germany (1992–1995), a research project “Laser cleaning of stained glass windows” was launched in 1997 with the aim to facilitate systematic investigations within an interdisciplinary co-operation

The application of lasers for the removal of superficial deposits from historic stained glass is a comparatively new field of scientific interest. Experimental studies concerning the behaviour of glass substrates and the corresponding superficial dep
