A laser consists of an active element that provides the energy levels for the laser transition, mirrors that allow control of the laser process through cavity response and finally a pump source that provides the necessary energy. It’s known that the luminosity of laser is quite high, which can reach up to billion times of that of the sun or even higher. It’s pure and with excellent mono-chromaticity. It has unparalleled collimation (travel in straight lines). Laser has great power; the burst ... Read more
