High finesse optical cavities have been the backbone of realizing narrow linewidth lasers to drive coherent excitations on dipole-forbidden transitions in atoms and ions for applications in atomic ...

Abstract: We demonstrate phase locking of a large group of blue emitters in an array of broad-area laser diodes with filtered optical feedback. Experimentally retrieved parameters from the far-field ...

Single-cavity, dual-comb lasers are those specially designed mode-locked lasers that can emit more than one, asynchronous ultrashort pulse trains with stable repetition frequency difference between ...

Synchronization among interacting entities is a process that underlies the function of numerous systems, including circadian clocks and laser arrays. It is generally believed that homogeneity among ...

Edited by Myriam P. Sarachik, The City College of the City University of New York, New York, NY, and approved January 22, 2020 (received for review September 10, 2019) Transient optical switching of ...

In the investigation of phase locking, emission measurements in the direction normal to the arrays were performed. Thus, we chose a second-order distributed feedback laser (DFB) structure for the ...

A phase-locked diode-laser system based on master-slave coupling of two-dimensional vertical-cavity surface-emitting laser (VCSEL) arrays by injection locking is presented. Frequencies and phases are ...
