Looks like a nice beam and heatsink to me
As far as using multimeters on low-value resistors go: give up.
By the way... I just realized that this type of lasers are illegal in Spain (I live in Spain, but I'm Bulgarian). So, what is your advice? Not taking it out and using it only at home? But the fun is watching the beam in the night... I'm sure there's a thread about this in the forum. If you could guide me to where I can get that info that'll be great. I don't want to get in trouble because of just having fun with a laser. And I understand that these devices are dangerous, that's why now that it works I'm concerned about this.
