Frequency doubled Nd:YAG lasers represent an attractive alternative to other laser tools for many material processing applications, but frequency doubling with pulsed Nd:YAG lasers has been performed until now only with pulses of tens of nanoseconds. In ma ...
In the ever-growing world of optical telecommunications. Semiconductor Optical Amplifiers (SOAs) are called to play an increasingly important role. Their attractive performances both in the linear and non-linear regime along with their reduced cost and sma ...
In order to improve the reliability of micro-spot welding of metal parts in production such as e.g. in electron guns for TV picture tubes, real-time information about the evolution of the welding process should be available to allow on-line modification of ...

The common configuration for deflecting laser beams in two dimensions is based on two single-axis galvanometric scanners placed perpendicular to each other. Over recent years, these fast scanners have proved to be both very reliable and very accurate. They ...
This thesis addresses general aspects of the operation of a coupled-cavity vertical surface-emitting laser (CC-VCSEL) which consists of two active cavities optically coupled and independently electrically pumped. The first two chapters of the thesis deal w ...
Considerable efforts are presently being made in the fabrication of miniaturized optical devices. An automated assembly technique for small optical components based on standardized holders and on-line alignment of the optical elements has been developed. T ...
Hot tear is one of the most serious defect which a casting can suffer. It represents a major limitation to the production of foundry cast parts and to the productivity of continuous casting processes such as the direct chiil casting of aluminium alloys. As ...
An automated assembly technique for small optical components has been developed. It concerns components such as, e.g., laser diodes and LEDs, fibers, lenses, beamsplitters, polarizers, mirrors, crystals, prisms, diffractive elements or photodiodes. It is b ...
Among all non-linear optical effects observed in single-mode optical fibres, stimulated Brillouin scattering (SBS) is of particular importance since it has numerous practical implications. SBS occurs when laser waves are scattered through the interaction o ...
