i want to make my own built using a aluminium diode housing and a 1.8W M140 445nm laser diode, Oclaro 700mW 638 Diodes (HL63193MG) and a N520 1W 520nm Green Laser Diode all from DTR
now i was wondering if i mount these diodes in the aluminium diode housings on a aluminium base plate do they need any electrical protection?
or is it already enough if the base plate is connected to ground?
