At the Fraunhofer Institute for Laser Technology (ILT), researchers in collaboration with RWTH Aachen University – Chair for Technology of Optical Systems (RWTH-TOS) are using a spatial light modulator (SLM) to shape the beam of an ultrashort pulse laser precisely into the desired pattern to apply to the surface of a workpiece.The developers say that this approach “significantly speeds up processi...
German researchers have developed a method for controlling and manipulating optical signals by embedding liquid crystal layers into waveguides created by direct laser writing. This work has produced devices capable of electro-optic control of polarization, which may open up possibilities for chip based devices and complex photonic circuits based on femtosecond write waveguides.Researcher Alexandro...
One vision for computing the future is to use ripples in magnetic fields as the fundamental mechanism. In this application, magnetic oscillators can be comparable to electricity and serve as the foundation of electronic products.In traditional digital technology, this magnetic system is expected to be much faster than today's technology, from laptops and smartphones to telecommunications. In quant...
A sketch of the imaging and holographic parts of a transient holographic microscope, including a pulse sequence, to illustrate the signal modulation method. By imaging the pinhole array at the sample position, a diffraction limited excitation spot array can be created, allowing for the simultaneous collection of transient data around 100 excitation spots.Femtosecond transient microscopy is an impo...
Recently, a group of researchers from the University of Cambridge developed an innovative method of using high-energy lasers to improve 3D printing of metals. This discovery has the potential to change the way we design and manufacture complex metal objects.3D printing has completely changed the landscape of the manufacturing industry. However, it faces obstacles, especially in terms of the charac...
