All-fiber coherent beam combining of fiber lasers

Optics Letters, 1999
One half of a 2x2 fused taper single-mode fiber coupler is used for the all-fiber spatial and spectral beam combining of two fiber lasers.

Coherent beam combining of diode arrays

2013 High Power Diode Lasers and Systems Conference (HPD), 2013
Summary form only given. There is continuing interest in increasing the power and improving the beam quality of laser sources for a variety of applications. An approach, particularly relevant to semiconductor and fiber lasers, is to beam combine large arrays of lasers.

Coherent beam combination in optical waveguides

SPIE Proceedings, 1990
A general theory for coherent coupling between two co-propagating or counterpropagating guided waves is formulated within the slowly varying envelope approximation. A pair of coupled nonlinear equations is obtained for the evolution of envelope functions. A numerical result is given for coherent coupling of two co-propagating pulses in a single mode

Coherent beam combination with single frequency dithering technique

Optics Letters, 2010
The single frequency dithering technique for coherent beam combination with one single modulation frequency and without a reference beam is presented for the first time to our knowledge. Coherent beam combination of four fiber amplifiers is successfully demonstrated by using the single-dithering technique. When the phase control system is in the closed

Beam quality factor for coherently combined fiber laser beams

Optics & Laser Technology, 2009
Abstract The beam quality factor for a coherently combined beam is studied in detail. A theoretical analysis and a numerical calculation are given to illustrate that the M 2 factor is not a proper means for evaluating the beam quality of a coherently combined beam. The beam propagation factor is introduced to evaluate the beam quality.

Coherent beam combining of fiber lasers

2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017
There is continuing interest in increasing the power and improving the beam quality of laser sources for a variety of applications including materials processing, pumping, power transmission, and illumination. One approach is to continue to develop improved lasers with higher power and good beam quality.
