Hey All,
I have built a DDL driver with a 5 ohm (2x10 in parallel: measured value=5.4) resistor and hooked it to my 405nm diode (New 250mW+ 405nm 6X High Power Blue-Violet Laser Diode - eBay (item 270750778133 end time May-31-11 19:19:53 PDT)), however no light comes out. My battery is a 9-volt, and it measures 9.48-9.50 without being attached to the circuit, but it measures 9.33-9.34 when it is attached, leading me to believe current is going through the circuit. Is my diode broken? If not, what is wrong with it?
Thanks to everyone in advance.
