Dear users, I`ve recently received my 200mW DX module. The negative cable (blue or black) has soldered out. When I was soldering it again, everything was ok but later it has moved and made contact with R4 resistance (the big one, light blue). The laser emited green light as usual for a very short while when this contact happened. It emits a red light from the diode (visible for the human eye) and with the camera I can see the typical violet infrared (808nm I guess) light.
Is the diode fried ? or the ktp ?
In yellow I`m showing the accidental contact that I`ve done.
I`ve another DX laser pointer 50mW (not the true 50mw one). Could I try to replace the KTP or the diode? Are the same components: 50mW (not true) laser pointer $14.99 and 200mW module $46.85 ?
The infrared does not heat, maybe the diode power has been reduced
Thanks for your help,
