The active laser medium (also called a gain medium or lasing medium) is the source of optical gain within a laser. The gain results from the stimulated emission of photons through electronic or molecular transitions to a lower energy state from a higher energy state previously populated by a pump source .
Additional advantages over traditional "dry" laser cutting are high dicing speeds, parallel kerf, and omnidirectional cutting. [14] Fiber lasers are a type of solid-state laser that is rapidly growing within the metal cutting industry. Unlike CO 2, Fiber technology utilizes a solid gain medium, as opposed to a gas or liquid. The “seed laser ...
Laser gain medium and type Operation wavelength(s) Pump source Applications and notes Dye lasers: 390-435 nm , 460-515 nm (coumarin 102), 570-640 nm (rhodamine 6G), many others Other laser, flashlamp Research, laser medicine, [2] spectroscopy, birthmark removal, isotope separation. The tuning range of the laser depends on which dye is used.
The gain medium is the major determining factor of the wavelength of operation, and other properties, of the laser. Gain media in different materials have linear spectra or wide spectra. Gain media with wide spectra allow tuning of the laser frequency. There are hundreds if not thousands of different gain media in which laser operation has been ...
In laser physics, gain or amplification is a process where the medium transfers part of its energy to the emitted electromagnetic radiation, resulting in an increase in optical power. This is the basic principle of all lasers. Quantitatively, gain is a measure of the ability of a laser medium to increase optical power. However, overall a laser ...
As in all neodymium-doped laser crystals, the lasing action of Nd:YVO 4 is due to its content of neodymium ions, which may be excited by visible or infrared light, and undergo an electronic transition resulting in emission of coherent infrared light at a lower frequency, usually at 1064 nm (other transitions in Nd are available, and can be ...
