Abstract: High-power, phased-locked, laser arrays as disclosed herein utilize a system of optical elements that may be external to the laser oscillator array. Such an external optical system may achieve mutually coherent operation of all the emitters in a laser array, and coherent combination of the output of all the lasers in the array into a single beam. Such an “external gain harness” system may include: an optical lens/mirror system that mixes the output of all the emitters in the array; a holographic optical element that combines the output of all the lasers in the array, and an output coupler that selects a single path for the combined output and also selects a common operating frequency for all the coupled gain regions.

Abstract: In a stabilized laser system, an output of a desired wavelength is generated. Each of a plurality of n lasers, which, while emitting light and having a preselected portion thereof fed back thereto, causes the fed back portion to be amplified and shifted in wavelength in a first direction which is spaced apart from the center wavelength of the feedback signal. A feedback stabilization arrangement is coupled to output ports of the plurality of n lasers for generating a feedback signal having a wavelength spectrum peaking at a wavelength shifted in an opposite direction to the first direction generated by the lasers in response to the feedback signal so as to provide an output signal at the output of the stabilized laser system having a wavelength spectrum that peaks essentially at the desired wavelength. A reflector is located at a predetermined signal round-trip time delay distance from the feedback stabilization arrangement. The reflector receives the output signal from the feedback stabilization arrangement and passes a first portion thereof therethrough, and reflects a remaining second portion back to the feedback stabilization arrangement as a secondary feedback signal that contributes to each of the plurality of n laser sources being set in a stable coherence collapse mode.

Abstract: A relatively high power fiber laser with an output wavelength in a spectral region considered to be “eye-safe” is disclosed. The high power fiber laser includes one or more fiber lasers that are fiber coupled, bundled and tapered into a multi-mode fiber. The multi-mode fiber is coupled into a hollow core, photonic band gap optical fiber filled with a Raman medium. In particular, fiber lasers formed from Yttrebium fibers having a nominal output wavelength of 1060-1120 nanometers are shifted to the eye-safe wavelength range by way of a hollow core photonic bond gap (PBG) filled with deuterium (D2) gas. Diode lasers having an output wavelength in the range of 940-980 nanometers can also be shifted to an eye-safe wavelength by direct Raman shifting of fiber coupled diode array to a hollow core PBG fiber filled with hydrogen (H2 gas). The use of the PBG optical fibers filled with various Raman medium for shifting the output wavelength of high power fiber lasers and diode lasers is relatively simple and inexpensive.
