The goal of our investigation is to design a low-speckle laser line generator based on partial spatially coherent laser light. Low speckle is achieved by exploiting a regime of strongly reduced spatial coherence of a broad-area vertical-cavity surface-emitting laser, which is used as the line generator’s light source. A comparative experimental study of different optical configurations is conducted, leading to the design of an optimal optical system. The results of our study are also valid for other sources of partial spatially coherent emission.
