Default Sanyo laser drive circuits

I downloaded a Sanyo laser diode catalogue thinking it'll only have some info about what they are pimping this year, but it turns out it contains alot more intresting info.

www dot photonic-products dot com/techinfo/sanyo_tech/sanyo_catalogue2008.pdf (i can't post proper links yet)

It has alot of more general information on laser diodes which many will find intresting and even some humerous advice like "4. Reselling, disassembling, or reverse engineering of a blue-violet laser diode is prohibited." 803T? :
It also includes a number of laser driver circuit diagrams, including one automatic current control and four automatic power control (photodiode feedback to keep a constant brightness) circuits which can be easily made by enthusiasts.

Some of them look like the sort of circuits you get on laser pointers.

Idd not which is why i implied they were similar and not identical.

Maybe some of the more electronics minded folk of this forum could adapt the circuits to better suit laser pointers? Like a self configuring blu-ray driver so you no longer have to worry about adjusting it for optimal power with the risk of burning it out.

Nice find. Good basic Laser diode do s and don't s info all in the same .PDF
Thanks.
