Zusammenfassung:	A pump system for a high-power holmium-doped fiber optic laser is provided, comprising: a 1.13 micron pumping means composed of: a coreless fiber and a light absorber; high and low reflection Bragg gratings at 1.135 microns, which form a ytterbium fiber laser cavity; high-power 915 nm laser diodes pumping the ytterbium fiber; and a high reflection Bragg grating (HR-FBG) at 2.07 microns; and a 2 micron laser formed by a holmium-doped fiber (HDF) that forms, with the high reflection Bragg grating at 2.07 microns, a holmium-doped fiber laser cavity, where each 915 nm photon of the 915 nm laser diodes that is converted into a 1.13 micron photon releases additional energy in the form of heat.
