A system for producing an optical gain, the system including a host having a light conducting path doped with thulium, holmium, and at least one rare earth selected from the group consisting of europium and terbium in respective amounts sufficient to produce an optical gain by energizing the thulium to a .sup.3 H.sub.4 state to produce an optical gain by a .sup.3 H.sub.4 -.sup.3 F.sub.4 transition, producing a 1.47 .mu.m wavelength output. There is subsequent energy transfer from the .sup.3 F.sub.4 state of the thulium to a .sup.5 I.sub.7 state of the holmium, and energy transfer from the .sup.5 I.sub.7 state to the rare earth selected from the group consisting of europium and terbium. The system can include oscillator, amplifier, and superluminescence source configurations. A method for making and a method for using the system are included.
An oscillator for oscillating the light from a light pump comprising:
A superluminescence source for use with a spontaneous light emission source comprising:
A method for using a optical fiber having a glass core, a first cladding circumferentially surrounding the core, a first endface, a first dichroic reflector coupled to the first endface, a second endface, and a second reflector coupled to the second endface, the glass core being doped with thulium, holmium, and at least one rare earth dopant selected from the group consisting of europium and terbium for oscillating the light of a light pump comprising the steps of:
