Description du projet
Une technologie innovante pour la caractérisation unique de pulsations laser ultracourtes
La capture du mouvement des électrons dépend de la disponibilité d’ondes lumineuses ultracourtes contenant seulement quelques cycles d’une oscillation lumineuse. De nos jours, de telles pulsations sont générées par les systèmes laser ultrarapides les plus modernes. La durée n’est pas le seul facteur clé pour atteindre une haute résolution temporelle: il faut également connaître la forme temporelle exacte de ces pulsations laser. Le projet FIELDTECH a pour ambition de développer un dispositif compact et convivial de diagnostic des pulsations, qui constitue une alternative solide et rentable aux complexes et coûteuses techniques actuelles basées sur une technologie du vide. Au-delà de la caractérisation précise des pulsations laser, la technologie développée dans le cadre de ce projet constitue une étape importante vers la prochaine génération d’électronique pétahertz ultrarapide.
Objectif
The proposed project is dedicated to bringing technology for next generation characterization of optical fields to a market level. The technology, based on recent innovations at LMU, will facilitate simple optoelectronic devices, for e.g. carrier-envelope-phase (CEP) measurements, enabling the characterization of few-cycle pulses at a single laser shot level. Contemporary CEP-meter techniques, i.e. the f-2f interferometer and Sterero-ATI technique, have limitations, including they do not easily offer extension of single-shot measurements towards increasing repetition rates (beyond 100 kHz), have limited operation wavelengths, or involve a sophisticated apparatus, which is bulky and expensive. Based on our recent innovation, the realization of a simple phase meter that consists of only a few components and can even work in ambient air, we propose to explore bringing this and also its related field-metrology technology to the market to overcome such limitations.
We aim to improve the long-term stability of the device, to enhance the signal sensitivity, and to decrease the temporal response time for high-repetition single-shot CEP detection and retrieval. These include a new design of the device structure, a proper encapsulation of the core device including electromagnetic shielding, the incorporation of fast electronics components, and the development of a user-friendly software. The newly developed device will undergo a series of tests with different ultrafast laser sources both in the near and mid-infrared wavelength range and at repetition rate up to at least 100 kHz. In parallel to the S&T development, we will carry out the ‘go-to-market’ activities, which include securing the IP, standardization and modulation of the product, the analysis of worldwide potential market, discovery of supply and distribution channels, and formulation of sales strategies.
