How to wire multiple laser diodes

Each driver likely has a connection for a feedback diode to sample the output and drive it correctly. If we''re talking laser drivers, they should all be run in parallel, so that each one can minister

FAQ-1: can I run multiple laser diodes on the same power supply?

This configuration works because when connected in series diodes share the same current. In contrast, when two diodes are connected in parallel, the current is no longer shared between the two diodes.
