Thanks a lot Bostjan. The problem I see with buying diodes from eBay or Amazon, is that I wasn't sure whether the energy levels that the sellers advertise with are reliable. In other words: whether I would be buying what I hope to buy in terms of energy levels. And it is important to me that the...
Good day,
I was planning to build a laser (device) with a wavelength of around 630NM, and a defocused beam, with a beam width of approx. 15mm (at around 3-4 cm of the diode), with different power settings and a maximum energy level of roughly 250mW. I wanted to build a second infrared laser...
