I can't seem to figure out how to tune this laser pointer. Any help?

I don't understand your question. Are you having trouble getting the diode to lase? The driver looks like one that might be used to drive a 532nm pump diode. If so, it likely won't get a high enough forward voltage to start the laser diode in this case.

Agree with the above - not clear- what do you mean by "tune" the pointer? Is not a pointer just a module and driver.

What is it you want to do?

For tuning try a pitch pipe. Tuning forks work too.

Probably wants to pot mod it. Probably has a cheap, fixed, switching driver.

Hi D,
I PMed him of what was needed to do, Need to see the other side of the driver. It's just not said and done for the inexperienced you need equipment. Or pay a member to do that for him, without buying all the needed items to do so.
