The dual wavelength pumping scheme controls the relative population of the termination state vis-a-vis the metastable state. Praseodymium doped chalcogenide glass and a variety of thulium doped glasses are described as examples. The relative pump powers or wavelengths may be adjusted to control the gain spectrum of the amplifier, making the amplifier useful in a variety of different optical systems including wavelength division multiplexed systems.

Le schéma de pompage à double longueur d'onde commande la population relative de l'état résonnant vis-à-vis de l'état métastable. Du verre de chalcogénure dopé au praséodyme et une variété de verres dopés au thulium sont décrits à titre d'exemple. Les puissances de pompage relatives ou les longueurs d'onde peuvent être ajustées de façon à pouvoir commander le spectre du gain de l'amplificateur, rendant l'amplificateur utile pour une variété de systèmes optiques différents y compris des systèmes à multiplexage en longueur d'onde.
