No you need a test load. No better option. You can build one pretty cheap or buy a premade one. Not having a solid secure connection between your diode and driver can lead to diode death like putting a DMM in there.

If you don't want to deal with setting up your driver grab a driver like a preset X-drive. If you do get an X-drive ditch the filtering cap as I am not sure what that is doing to it and a proper laser driver will not need it.:beer:

If you connected it directly to a DMM there is a good chance you have damaged it. :yabbem:

You need a test load to figure out what you have and if it does still work to set it to the proper current.
