Diode laser

Une diode laser est un composant opto-électronique à base de matériaux semi-conducteurs. Elle émet de la lumière monochromatique cohérente (une puissance optique) destinée, entre autres, à transporter un signal contenant des informations sur de longues distances (dans le cas d'un système de télécommunications) ou à apporter de l'énergie lumineuse pour le pompage de certains lasers (lasers à fibre, laser DPSS) et amplificateurs optiques (OFA, Optical Fiber Amplifier).

Tunable laser

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 solid state. Among the types of tunable lasers are excimer lasers, gas lasers (such as CO2 and He-Ne lasers), dye lasers (liquid and solid state), transition metal solid-state lasers, semiconductor crystal and diode lasers, and free electron lasers.

Fiber laser

A fiber laser (or fibre laser in Commonwealth English) is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, thulium and holmium. They are related to doped fiber amplifiers, which provide light amplification without lasing. Fiber nonlinearities, such as stimulated Raman scattering or four-wave mixing can also provide gain and thus serve as gain media for a fiber laser.
