Abstract
(Englisch)
|
Emerging and current applications in biomedical photonics, sensing, microscopy and micro machining, to name only a few, could take large profit from the availability of industry-ready short optical pulse sources in the tens-of-microjoule pulse energy level. Our Swiss company is well positioned from the point of view of R&D know-how and from the experience we have in transferring results from research into commercial products fabricated in Switzerland and sold world-wide. This project wants to address amplification of ultrafast optical pulses in fibre-based amplifier setups in the frame of the Action COST 299 and to share the results with our COST colleagues. In the first year of the two-year project we have performed theoretical and experimental investigations in order to advance the development of a master-oscillator fibre-power-amplifier (MOPA) system that can deliver clean, high pulse energy (microJoule range), short (down to 1 ps), stable optical pulses in the wavelength range above 1 micrometer. We found that amplification of picosecond gain-switched lasers is possible in fiber amplifier configuations with more than 30 dB overall gain, reaching up to 10 nJ pulse energies. This exceeds our first year target of 23 dB gain and makes us confident that we reach the overall goals of the project.
