Improving on previously published room-temperature large-area photonic crystals (PhCs) Quantum cascade lasers (QCLs), researchers from ETH Zurich have fabricated a device with 5W surface-emitting peak power when driven in pulsed operation. by Julien Happich @ eenewseurope.com Their...

The Slamtec Mapper has two models with a detection range of 20m and 40m. It can easily map for home scenes or commercial, light industrial scenes. The following picture shows the M1M1 map function with a 134 meters * 111 meters underground parking lot. In the handheld mode, the...

Laser technology from Osram transforms smartphones into beamers. Green lasers for projector applications need to have not only outstanding beam characteristics but also a high optical performance in order to deliver sharp and bright images. Although a projector also needs red and blue...

Buildlog.Net Blog published a new project. It's an ESP32 Controller board used to control X/Y and Z axis of Pen or Laser engraving machines. I have done several pen and laser machines lately, so I decided to create a custom PCB for Grbl_ESP32 for these types of machines. This is a...

A team led by the Technical University of Munich (TUM) physicists Alexander Holleitner and Reinhard Kienberger has found success for the first time in generating ultrashort electric pulses on a chip. They made this possible by using asymmetric metal antennas only a few nanometers in...

Cellphone chargers have been in existence for years and have grown from one stage to another. It started with the mobile phone traditional charger which had a USB interface, a DC converter, and a charging plug and now has expanded to a close-range inductive wireless charging. The commonly...

A synchrotron is a particular type of cyclic particle accelerator which is used to accelerate quantum level charged particles at a very high velocity, traveling around a fixed closed-loop path. It is one of the first accelerator concepts to enable the construction of large-scale...

A group of researchers led by Nick Vamivakas from the University of Rochester has successfully produced particles which have negative mass in an atomically thin semiconductor material. According to the researchers, they have created a device that can generate LASER light using a...
