After replacing laser diode 9mm 808nm 1W CW, is it necessary to change from driver board? bcz i am not getting blue output.
If i place original diode it is outputting perfectly.
I would recommend at least a 2W pump diode for 100mW of 473nm. Also, since 473nm technology is so temperature sensitive, once you align the diode you'll need to retune the diode temperature by tweaking the diode TEC pot.
Also, if you're interested in building a portable/pointer style lasers search the forum for 445nm drivers and builds to see how other people are doing it..
This is the second of someone elses threads that you have posted this in. Start your own thread in the drivers section or go with the drivers that have already been suggested to you by Jander6442.
