Researchers at the Federal College of Technology in Lausanne (EPFL) have shown that femtosecond lasers suitable for palm size can be manufactured using glass substrates.Can femtosecond lasers made entirely of glass become a reality? This interesting question prompted Yves Bellouard, the head of the Galata laboratory at the Federal Institute of Technology in Lausanne, to embark on a journey after y...
Chip level ultrafast mode-locked laser based on nanophotonic lithium niobate.Researchers have created a compact mode-locked laser integrated into a nanophotonic platform, capable of generating high-power and ultrafast optical pulses. The breakthrough in miniaturization of MLL technology can significantly expand the application of photonics.Innovation in mode-locked laser technologyTo improve the t...
The rapid development of photonic integrated circuits (PICs) has combined multiple optical devices and functions on a single chip, completely changing optical communication and computing systems.For decades, silicon-based PICs have dominated the field due to their cost-effectiveness and integration with existing semiconductor manufacturing technologies, despite their limitations in electro-optic ...
Laser cladding technology, also known as laser additive manufacturing technology, uses high-energy laser as the heat source and metal alloy powder as the cladding material. Through the synchronous action of laser and alloy powder on the metal surface, it quickly melts to form a molten pool, and rapidly solidifies to form a dense, uniform, and controllable thickness metallurgical bonding layer, the...
Creating new laser systems for use in spectroscopy applications is a challenging and costly endeavor. In order to give even small and medium-sized enterprises access to such innovative technology, the Fraunhofer Institute for Reliability and Microintegration (IZM) co-launched the QuantumCascade project to develop a modular laser system for a range of multispectral analytics.This week the IZM repor...
