Lézerfajták

Lézerfajták refers to the different types of lasers. Lasers are categorized based on several factors, including the gain medium used, the wavelength of the emitted light, and the operating principle.

One common classification is by the gain medium. Solid-state lasers utilize a solid material, such as ruby or neodymium-doped yttrium aluminum garnet (Nd:YAG), as the active medium. Gas lasers, on the other hand, employ a gas mixture, like helium-neon (HeNe) or carbon dioxide (CO2), to generate laser light. Semiconductor lasers, also known as diode lasers, use a p-n junction in a semiconductor material. Dye lasers use organic dyes as the gain medium, allowing for tunable output wavelengths. Fiber lasers use optical fibers doped with rare-earth elements.

Another way to categorize lasers is by their output wavelength. This can range from ultraviolet (UV) to infrared (IR) and even into the terahertz (THz) region. The wavelength is determined by the energy transitions within the gain medium.

Lasers can also be classified by their mode of operation. Continuous-wave (CW) lasers emit a constant beam of light, while pulsed lasers emit light in short bursts. Pulsed lasers can be further divided into Q-switched and mode-locked lasers, which produce very high peak power pulses. The choice of laser type depends heavily on the intended application, such as scientific research, industrial manufacturing, medical procedures, or telecommunications.
