Abstract
A pump laser capable of delivering at least a specified amount of output power is described. The pump laser has an array of N semiconductor lasers each having a first wavelength and an individual available output power (P) such that the product of N times P is equal to or greater than the specified amount of output power. The pump laser also has a coupler configured to couple light emitted by the individual lasers in the array to an individual optical fiber.
