Very grateful for your reply. Have you seen any journal publications to support this? Considering how ubiquitous laser diodes are, I find it strange that there are hardly any search results for this topic.

Most of the spec sheets for laser diodes quote the divergence values at specific output power (say 100mW) measured at FWHM (50% intensity). But none of the spec sheets which I have seen mention anything about how the divergences are affected when the output power changes.

Thank you. I should have mentioned that I am interested in the diodes extracted from Blue-ray drives. Do you think they have variable divergence values?

Dear readers, What happens to the divergence values (along and perpendicular to the emitting surface) when the driving current is increased or the output power is increased. Does the divergence: Increase along one axis Increase along both axes Decrease along both axes Decrease along one...
