We have developed a new technique for high-count fiber array connector production. Fully automated manufacturing was demonstrated for 500-count arrays with 250µm center-to-center spacing and sub-micron placement for arbitrary fiber type in any 2D co

In this work, a high-resolution, self-heterodyne,RF measurement of a broad-area laser is spatially resolved using an optical fiber at a range of power levels. Three separate spatial regimes of operation are revealed as power is increased: conventiona

Applying a pseudo-random binary sequence (PRBS) to phase modulators is a recent development in the broadening of optical spectra of laser sources to defeat stimulated Brillouin scattering (SBS). The theoretical underpinning of this method relies on a

This paper reveals some limitations from the practical implementation of applying the pseudo-random binary sequence (PRBS) method to the modulation of optical spectra as a means to increase stimulated Brillouin scattering threshold in high power lase

For the first time, a completely spectrally resolved model is used to study SBS for nontrivial spectra. A deeper understanding of Brillouin gain and new physics are revealed, including Stokes tone shifting, broadening, and splitting.

The emission spectrum of a 10-W commercial broad-area laser operated at full power was narrowed and stabilized by coupling an off-axis portion of its far-field emission to a single-mode fiber Bragg grating. The feedback produced in this partial compo

This work presents a comparative review of two classes of advanced, ultrafast, fiber lasers: dissipative soliton resonance (DSR) oscillators and Mamyshev oscillators. These two classes have received significant attention in recent years and have argu

An improved fiber amplifier model for simulating thermal mode instability (TMI) in high-power fiber amplifiers is developed. The model is applied to reveal new physics regarding the thermal physics that is critical to the TMI process, which are not t

Coaxial fiber lasers, consisting of a Ho-doped core surrounded by a Tm-doped ring, are studied via experiments and numerical simulations. Previous simulations indicated that coaxial fiber lasers have the potential to reach power conversion efficienci
