Laser Etching PCBs

A while ago, [Marco] mounted a powerful laser diode to a CNC machine in an attempt to etch copper clad board and create a few PCBs. The results weren’t that great, but the technique was promising. In ...

A 342-nm ultraviolet AlGaN multiple-quantum-well laser diode

Ultraviolet laser diodes (UV-LDs) and light-emitting diodes (LEDs) with GaN, AlGaN or AlGaInN active layers can emit light at a wavelength shorter than 365 nm due to GaN having a large bandgap energy ...
