How hot can a laser get

WebThe parallel rays of coherent light from the laser source often fall in the range between 0.06–0.08 inches (1.5–2.0 mm) in diameter. This beam is normally focused and intensified by a lens or a mirror to a very small spot of about 0.001 inches (0.025 mm) to create a very intense laser beam. WebA: There could be a few reasons why the laser power might drop by a few mW: 1. The laser is getting some back-reflections and these are having an impact on the internal photodiode response. The photodiode ‘sees’ more light and triggers …
