A novel, highly accurate, all electronic technique for phase locking arrays of optical fibers is demonstrated. We report the first demonstration of the only electronic phase locking technique that doesn't require a reference beam. The measured phase

In this paper, we investigate two approaches to multitone seeding of high-power ytterbium-doped amplifiers using a symbolic and numerical code that solves a two-point boundary problem. Optimization of amplifier action through wavelength separation an

A dual seeded (pump at 1069 nm and second Stokes at 1178 nm) Raman laser system involving amplification of the second Stokes in a Raman resonator having high reflector Bragg gratings tuned to the first Stokes at 1121 nm is proposed. This system has t

A novel 50 W narrow linewidth 1178 nm Raman laser involving amplification of the second Stokes in a 1121 nm resonance cavity is reported. 1121 nm cavity power along with Stimulated Brillouin Scattering are important design considerations.

Significant effects from heating occur in both single and two tone fiber amplifiers. Single tone 1064 nm amplifiers have highest efficiency when the external environment surrounding the gain fiber is cold while 1064 nm two tone amplifiers co-seeded w

The efficiency of two tone fiber amplifiers can be changed rather significantly by altering the temperature of the external environment surrounding the gain fiber. It is shown experimentally that changes in the temperature of the core of the gain fib

We present experimental verification of a novel technique to suppress stimulated Brillouin scattering (SBS) in single frequency fiber amplifiers. This technique relies on seeding with a combination of broadband and single frequency laser beams to all
