Applied Sciences, 2019 Filter-based spectral beam combining (FSBC) is a promising power-scaling concept for high-power, broad-linewidth fiber lasers, as it relaxes the requirements for linewidth control and also the sizes of the individual beams.

High-Power External Spatial Beam Combining of 7-Channel Quantum Cascade Lasers Emitting at ~8.5 μm
PhotonicsBased on the demand for high-power output, a spatial beam combining 7-channel quantum cascade lasers (QCLs) is demonstrated in this paper. A “2 + 3 + 2” stepped structure is designed to convert the seven beam spots into a circular arrangement.

The generation and verification of Bessel-Gaussian beam based on coherent beam combining
Results in Physics, 2020 We propose a method to generate Bessel-Gaussian (BG) beam by Gaussian beam array where beamlets are arranged along a circle. The phase difference between adjacent beamlets is a constant, and the total phase increment is equal to 2πl (l is integer). Based

Enhanced Supermode Stability in Weakly Anti-Guided Dual-Cavity Photonic Crystal VCSEL Arrays
IEEE Photonics JournalWe report on 940 nm dual-cavity photonic crystal vertical-cavity surface-emitting laser (VCSEL) arrays fabricated at a commercial foundry. These arrays leverage an anti-guided design enabled by reduced electrical resistance between optically coupled ...

Interferometric beam combination with discrete optics [PDF]
Optics Letters, 2010 We explore the capabilities of discrete diffraction in phase retrieval problems and propose an innovative scheme exploiting a two-dimensional array of coupled waveguides to determine the phase and amplitude of the mutual correlation function between any pair of three telescopes of an astrointerferometer.

Design of a 36-W fiber-coupled green laser diode by Zemax
Results in Physics, 2018 We propose a design of a 36 W fiber-coupled green diode laser based on TO-Can packaged emitters using Zemax. This is achieved by beam collimation, spatial beam combining, polarized beam combining and fiber coupling.

Non-Iterative Ring Beam Shaping Using Phase Control in Coherent Beam Combining [PDF]
EPJ Web of ConferencesWe propose a deterministic method for ring-shaped beam synthesis in coherent beam combining (CBC) systems using phase-only control. A calibrated propagation operator is inverted via a Tikhonov-regularized pseudoinverse to directly compute the required ...
