Generation of Partially Coherent Beams
TL;DR: Partially coherent beams with a prescribed phase, state of polarization, and degree of coherence display many extraordinary propagation properties and are preferred in many applications, such as particle trapping, free-space optical communications, remote sensing, optical imaging, material thermal processing, image transformation, and optical encryption as discussed by the authors.

Experimentally generating any desired partially coherent Schell-model source using phase-only control
TL;DR: In this article, a phase-only liquid-crystal spatial light modulator (SLM) was proposed to control both the phase and amplitude using a single SLM, thereby making the amplitude filters unnecessary.

Generalized multi-Gaussian correlated Schell-model beam: from theory to experiment
TL;DR: A new kind of partially coherent beam with non-conventional correlation function named generalized multi-Gaussian correlated Schell-model (GMGCSM) beam is proposed and experimental results verify theoretical predictions.
