What is the laser types?

There are several types of lasers, categorized mainly by the medium used to generate laser light. Common types include solid-state lasers (like Nd:YAG), gas lasers (such as CO2 and helium-neon lasers), dye lasers, and semiconductor lasers (like laser diodes). Each type has unique properties and applications, ranging from industrial cutting and medical procedures to telecommunications and entertainment. Additionally, lasers can be classified based on their operation modes, such as continuous-wave (CW) and pulsed lasers.
