A Laser Treatment To Improve Paper Electronics
https://www.electronics-lab.com/laser-treatment-improve-paper-electronics/
“NanoEngineers” research group at Iowa University have been devoting efforts to use graphene and its amazing properties in their sensors and other technologies. Graphene has many extraordinary properties. It is about 100 times stronger than the strongest steel. It conducts heat and electricity efficiently and is nearly transparent. Inspired by some recent projects about using inkjet […]
Opto-isolated laser controller build
https://www.electronics-lab.com/opto-isolated-laser-controller-build/
Scott Harden built his own opto-isolated laser controller and wrote a post on his blog detailing its assembly: My goal was to utilize a free hardware output line to signal to a device that I build to modulate the laser in a special way. This way there would be no modification to any existing equipment, […]

by Julien Happich @ edn-europe.com Published in Applied Physics Letters under the title “Sub-wavelength InAs quantum dot micro-disk lasers epitaxially grown on exact Si (001) substrates”, the findings from an international team of researchers opens a new route to CMOS-compatible on-chip laser integration. The researchers designed subwavelength micro-disk lasers (MDLs) as small as 1μm in […]
‘Soldering’ with a laser
https://www.electronics-lab.com/soldering-with-a-laser/
Thijs Beckers @ elektormagazine.com writes about a new experimental method of connecting electronics components together using a laser beam. Researchers from the University of Saarland have, together with colleagues from Helsinki, discovered a new material which can connect electronic components together using a chemical method. Multiple very thin layers (1000x thinner than a human heir) […]
Arduino – Processing Laser CNC Project
https://www.electronics-lab.com/arduino-processing-laser-cnc-project/
Neumi @ github.com has build an Arduino based CNC project and source files are provided. This is my scratch build Laser CNC Engraver and PCB Exposer. It uses a 150mW 405nm laser diode and two CD drive motors and mechanics. A Processing sketch calculates the position of the pixels and send them to an Arduino Mega, […]
Lasers built on silicon are a step towards fully integrated photonics
https://www.electronics-lab.com/lasers-built-on-silicon-are-a-step-towards-fully-integrated-photonics/
A group of researchers from the Cardiff University has demonstrated the first practical laser that has been grown directly on a silicon substrate. by Graham Prophet: The lasing structure was formed in indium arsenide/gallium arsenide layers grown directly on a silicon substrate; the research group notes that previous work has involved wafer bonding techniques to […]
Arduino-Powered Laser Engraver
https://www.electronics-lab.com/arduino-powered-laser-engraver/
MichielD99, a 16 year old Belgian teenage maker build this amazing laser engraver using Arduino UNO, two NEMA-17 stepper motors and stepper motor drivers. This laser engraver uses a 1.8W 445nm laser module, of course, this is nothing compared to the industrial laser cutters who use lasers of (a lot) more than 50W. But this […]
