“…Thus, the power densities were 2.13 Gw/cm 2 , 3.54 Gw/cm 2 , 4.95Gw/cm 2 . The radiance density (laser beam brightness) parameter as determined using our previous method [27][28][29] equated to 0.46, 0.77 and 1.09 (W. Cm 2 .Sr.μm) respectively as detailed in Table .1. The water layer was used as the confinement layer, while absorbtive layer was polyvinyl black tape.…”

“…Several workers in recent time have worked with high brightness lasers for processing materials [20,21,[28][29][30][31][32][33][34][35][36]48,50,54,56,58]. Wallace [20] used the high brightness diode laser to produced high efficiencies and lower operating costs.…”

a b s t r a c tThis paper details the importance of brightness in relation to laser beams. The 'brightness' of lasers is a term that is generally not given much attention in laser applications or in published literature. With this said, it is theoretically and practically an important parameter in laser-material processing. This study is first of a kind which emphasizes in-depth, the concept of brightness of lasers by firstly reviewing the existing literature and the progress with high brightness laser-material processes. Secondly, the techniques used to enhance the laser beam brightness are also reviewed. In addition, we review the brightness fundamentals and rationalize why brightness of lasers is an important concept. Moreover, an update on the analytical technique to determine brightness using the current empirical equations is also provided. A modified equation to determine the laser beam brightness is introduced thereafter. Furthermore, research studies previously conducted to modify laser design to affect laser beam brightness are also discussed. The paper not only involves a review of the techniques used to improve laser beam brightness but also reviews how bright lasers can be employed to enhance/improve laser process capabilities and cost reduction of the laser assisted processes in manufacturing.
