Hello everyone!
I’m trying to get an old laser diode working but I’m not sure how. The laser diode comes from an old 3D-printer (Davinci Pro), I got some parts of it when it was scrapped. I did not get the main board.
The laser is specified for 350mW and has 4 leads coming of it. I’ve not been able to find any info about the laser.
The leads seem to come in pairs, one diode between each lead pair. I assume that one is the laser diode and the other is for temperature measurement, maybe?
I’m not sure how I’m supposed to verify this without destroying the laser, I don’t own a low power constant current driver and I don’t want to accidentally destroy a temp sensor.
Below are some measurements and images of the device.
Side note.
I’m planning on using this to cut PCB stencils out of thin plastic films like Kapton. I know that the printer originally came with Kapton film for this type of use but never tried it myself.
So the second question would be if anybody knows of a cheap alternative to Kapton film, I don’t want to buy a huge roll of it nor do I want a tape.
Thanks for any suggestions!
