US Classification:

35934131, 359134, 359337, 359345, 372 70

Abstract:

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.

Specifically, the present invention discloses a glass composition comprising in mol % on the oxide basis, of 0-40% R O where R includes the alkali metals (Li, Na, K, Rb or Cs) as well as Ag and Tl, 0-20% XO where X includes the alkaline earth metals (Mg, Ca, Sr or Ba) as well as Cu, Zn, Cd and Pb, 15-80% MoO +WO , 0. 5-60% Sb O , and 10-40% P O. Additionally, the Sb-stabilized Mo+W phosphate based glass composition can contain a total of 0-5%, in mole percent (mol %) on the oxide basis, of glass forming oxides including, but not limited to, B O , Al O , SiO , TeO , Ga O3, GeO , transition metal and rare earth metal oxides, or mixtures thereof. The resulting durable Sb-stabilized Mo+W phosphate based glass compositions are particularly useful as refractory adhesives, sealing glass frits, and overcladding material for glass fiber.
