Just a bit of mechanical pr0n really, a pair of 445nm modules I made recently.
A pair of diodes and a set of prisms for correction in each one, with Aixiz collimators along with ~15% other losses in steering mirrors, knifing, prisms and output window, they spit out about 1.8W each with 4mm/1mR beams and space for peltiers if required at a later date.
