Expensive semiconductor laser diodes have no tolerance for fast voltage or current transients. To minimize the risk of damage, a standard JFET-clamp circuit shorts the laser when there is no supply ...

Plaintiff SEMICAPS filed suit in the Northern District of California, alleging infringement of U.S. Patent No. 7,623,982, which relates to the testing of electronic circuits using a laser. The ...

The project describes the operation of a cheap keychain lasers that are being sold in low price. In theory, most common laser heads contains two semiconductors inside which includes a laser diode (LD) ...

Taken from the 2022 Physics World Optics and Photonics Briefing, where it appeared under the headline "Inscribing the way to a brighter future". VitreaLab, a photonics start-up based in Vienna, was ...

This circuit was designed to meet a medical application’s requirement to drive a laser diode with reasonable precision and a minimum of components and footprint (the device is now in clinical trials).

Researchers transformed red marker ink into graphene-based circuits using a laser, enabling low-cost, flexible electronics on everyday surfaces like paper or cups. (Nanowerk News) It is the first case ...

In this episode of the Physics World Weekly podcast, we meet Jonas Zeuner, who is co-founder and managing director of the Austrian start-up company VitreaLab. He explains how the firm’s laser-powered ...

For those who wish to go beyond through-hole construction on perfboard for their circuit boards, a printed circuit board is usually the next step up. Allowing for things like surface-mount components, ...
