Claim Text:
1. A system for optical amplification, the system comprising: an optical fiber comprising a core surrounded by a cladding, the core comprising a gain medium characterized by a gain spectrum; a seed light source, in optical communication with the core, to transmit seed light, at a first wavelength in the gain spectrum, into the core of the optical fiber so as to amplify the seed light, the seed light having a first linewidth greater than 100 MHz; a control light source, in optical communication with the core, to transmit control light, at a second wavelength in the gain spectrum, into the core so as to reduce a peak rate of heat deposition per unit length along the optical fiber, the control light having a second linewidth greater than 100 MHz; and a pump source, in optical communication with the optical fiber, to transmit pump light at a pump wavelength into the fiber so as to pump the gain medium and amplify the seed light.
