What is the difference between the XJA-130 diode and the XJA-140 diode?
A. Without going into too much technical detail, the XJA-140 diode is capable of CW output of 1,250mw driven conservatively by a standard DrLava Micro Boost driver board. This means that any LASER you build with this diode has the capability of (at least) 25% more output power than the XJA-130 diode used in the Spyder III Arctic.
