What is the pinout of a 4-pin laser diode?

Question

Do it yourself

Here is a diode I picked out. Does anyone know his pinout? Really needed. You can only say where food and land are, the rest of the legs are not needed. I can upload pics from a different angle if needed.

Answer 1

There are sources with two lasers and one photodiode - just with 4 legs. Here it would be nice to see how it was connected, in order to at least find the ground. And then, according to the circumstances, call the diodes, and if this is for a home-made cutter, supply the correct power and see what is on. I did this with a diode from the printer, but it was in a round case, so the pinout is different. The main thing is that the diode survived and made me happy for some time). Until you get bored).
