Rod lasers – an old term for a true specialist
The term "rod laser" is hardly used these days. It only describes the design of the laser and defines the laser medium which consists of a rod-shaped crystal.
Rod lasers are available with different power levels, depending on the crystal as a medium. Simply put: the bigger, the more powerful.
Rod lasers are still in use. Pulsed rod lasers, for example, can be used for fine welding tasks or fine cutting tasks.
The technical terms for these processes are laser welding and laser cutting. Disadvantage of rod lasers: They require good cooling via correspondingly massive heat sinks. This in turn, experts say, reduces their performance.
