title = "Semiconductor laser beam quality metrics for free-space optical communications",
abstract = "The beam propagation factor, M2, exists as one of very few measures of a laser's performance, when really a more detailed analysis of the application and laser are necessary for judgement in most cases. In free-space optical communications, a crucial figure of merit is the proportion of diffraction-limited power in the farfield. A calculated structure has been made with a higher proportion of diffraction-limited power in the farfield than another calculated structure with a much better M2. This calculated structure has an M2 of 19, with 89% of its power within the diffraction limit in the far-field, compared to another calculated structure with M2 of 1.7 that has 86% of its power within the diffraction limit in the far-field.",
