1. Jan. 2022 · Types of lasers, according to the gain medium: Semiconductor lasers: the active medium is a direct semiconductor. Electrically pumped: diode lasers. In 2020 they account for the 42% of the total laser market. Solid state lasers: the active medium is a glass or crystalline "host" material, to which “dopants” are added.
Laser linewidth from high-power high-gain pulsed laser oscillators, comprising line narrowing optics, is a function of the geometrical and dispersive features of the laser cavity. To a first approximation the laser linewidth, in an optimized cavity, is directly proportional to the beam divergence of the emission multiplied by the inverse of the overall intracavity dispersion .

Semiconductor. Industry. Nanoelectronics. v. t. e. A semiconductor is a material that has an electrical conductivity value falling between that of a conductor, such as copper, and an insulator, such as glass. Its resistivity generally falls as its temperature rises; metals behave in the opposite way. [1]
A tunable laser is a laser whose wavelength of operation can be altered in a controlled manner. While all laser gain media allow small shifts in output wavelength, only a few types of lasers allow continuous tuning over a significant wavelength range. There are many types and categories of tunable lasers. They exist in the gas, liquid, and ...

Semiconductor laser, kadang-kadang disebut diode laser, laser yg tidak solid-state. Perangkat elektronik yg menggunakan ini umumnya sangat kecil dan menggunakan daya yang rendah. Mereka dapat dibangun menjadi array yang lebih besar, seperti sumber penulisan dalam beberapa printer laser atau CD player.
Liquid organic dye laser system excited by a copper vapor laser. An organic laser is a laser which uses an organic (carbon based) material as the gain medium. The first organic laser was the liquid dye laser. [1] [2] These lasers use laser dye solutions as their gain media. Organic lasers are inherently tunable and when configured as optimized ...
