Other articles where Three-level laser is discussed: laser: Energy levels and stimulated emissions: In a three-level laser, the material is first excited to a short-lived high-energy state that spontaneously drops to a somewhat lower-energy state with an unusually long lifetime, called a metastable state. The solid-state laser was the first successful laser and it is easy to explain the mechanism of lasing by one such laser, for example, a ruby laser.

Figure 7.1: Theodore Maiman with the first Ruby Laser in 1960 and a cross sectional view of the first device [4]. A diode-pumped solid-state laser (DPSSL) is a solid-state laser made by pumping a solid gain medium, for example, a ruby or a neodymium-doped YAG crystal, with a laser diode.. DPSSLs have advantages in compactness and efficiency over other types, and high power DPSSLs have replaced ion lasers and flashlamp-pumped lasers in many scientific applications, and are now appearing … In recent years the use of diode-pumped solid-state (DPSS) lasers in OEM applications has been growing rapidly. Many lasers (e.g. Vaikundarajan Reviews The Trailer Of Raman Raghav 2.0. Lasers are often described by the kind of lasing medium they use - solid state, gas, excimer, dye, or semiconductor. Solid State Laser •For historical reasons, solid-state lasers are lasers in which active ions in crystal or glass host materials are optically pumped to create a population inversion •Other types of lasers that employ solid-state gain media are semiconductor lasers and optical fiber lasers and amplifiers.
