Angle-Etched Facet Laser Arrays (Fan Laser Arrays)
We present a novel individually addressable diode laser array that uses angle-etched facets. By arranging the lasers in a fan-like structure, all lasers emit in different directions from a common effective aperture. Using this device design, we demonstrate lasers with beam directions that are fixed and distinct, stable, single mode, and capable of simultaneous and random access operation. We an...
متن کاملParallel Simulation of Semiconductor Laser Arrays
A parallel Hopscotch algorithm for the simulation of semiconductor laser arrays which overlaps the computations and communications is presented. The method uses a Lax-Wendroff scheme for the hyperbolic part of the operators and allows to obtain near-to-perfect speed-ups on MIMD computers. Numerical experiments indicate that semiconductor laser arrays exhibit a rich dynamic behavior ranging from...
متن کاملAdvances in semiconductor laser bars and arrays
Advances in high power semiconductor lasers such as increased spectral brightness, increased spatial brightness, and reduced cost architectures at wavelengths from the near infrared to the eye-safe regime have the potential to dramatically improve diode pumped systems and enable new direct diode applications. Data are presented which demonstrate both edge emitter devices and high power surface ...
متن کاملBeam combining of quantum cascade laser arrays.
Wavelength beam combining was used to co-propagate beams from 28 elements in an array of distributed-feedback quantum cascade lasers (DFB-QCLs). The beam-quality product of the array, defined as the product of near-field spot size and far-field divergence for the entire array, was improved by a factor of 21 by using wavelength beam combining. To demonstrate the applicability of wavelength beam ...
متن کاملRobust synchronization in fiber laser arrays.
Synchronization of coupled fiber lasers has been reported in recent experiments [Bruesselbach, Opt. Lett. 30, 1339 (2005); Minden, Proc. SPIE 5335, 89 (2004)]. While these results may lead to dramatic advances in laser technology, the mechanism by which these lasers synchronize is not understood. We analyze a recently proposed [Rogers, IEEE J. Quantum Electron. 41, 767 (2005)] iterated map mode...
