Highly efficient one- and two-cascade Raman lasers based on phosphosilicate fibers

René Salathé, Hans Georg Limberger, Florian Dürr, Marcel Zeller

Characteristics of one-cascade (1.06 double right arrow 1.24 mum) and two-cascade (1.06 double right arrow 1.24 double right arrow 1.48 mum) phosphorus-doped fiber Raman lasers are studied. The cavities of both lasers are formed by Bragg gratings written d ...

Optically addressing a large number of cantilevers

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart

A heterodyne laser Doppler interferometer operating up to 100 MHz with an optical vibration excitation function was implemented to enable frequency detection of nanocantilevers. By using the stimulant of a network analyzer to sweep the modulation frequency ...

Study of the beam path distortion profiles generated by a two-axis tilt single-mirror laser scanner

René Salathé, Thomas Sidler, Moustapha Hafez

Beam distortion profiles are studied for scanning devices that have a single mirror with two rotational degrees of freedom (DOF), also named tip/tilt scanners. The case of a fast steering scanner used for high power material processing applications is stud ...

Coherent optical information systems

Demetri Psaltis

Coherent optical beams are used to communicate, store, and process information in a growing number of applications. The availability of coherent laser sources is of critical importance for the realization of such optical information systems. An incoherent ...

Holographic techniques for recording ultrafast events

Demetri Psaltis

In this paper we report on a holographic method used to record fast events in the nanosecond time scale. Several frames of the expansion of shock waves in air and in a polymer sample are recorded holographically in a single shot experiment, using a pulse t ...

Characterisation and origin of arc fluctuations in a F4 DC plasma torch used for thermal spraying

Christoph Hollenstein

The fluctuating behaviour of a Sulzer Metco F4 DC plasma gun has been investigated. The time dependencies of the arc voltage and current and of the optical emission of the plasma jet have been measured. An optical fibre inside the gun allows direct measure ...

Compact multisensor laser scanning head for processing and monitoring microspot welding

René Salathé, Thomas Sidler, Moustapha Hafez

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 ...

Compact fast-steering tip/tilt laser scanner for high power material processing applications

Moustapha Hafez

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 ...

Local annealing of shape memory alloys using laser scanning and computer vision

René Salathé, Yves Bellouard, Reymond Clavel, Thomas Sidler, Moustapha Hafez

A complete set-up for local annealing of Shape Memory Alloys (SMA) is proposed. Such alloys, when plastically deformed at a given low temperature, have the ability to recover a previously memorised shape simply by heating up to a higher temperature. They f ...

High power second harmonic generation with free running Nd : YAG slab laser for micro-machining applications

René Salathé, Thomas Sidler, Sébastian Favre

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 ...
