Just check with a multimeter. With all my 3 pin pots, two of them are inversely proportional.
e.g.
All the way clockwise might be Max resistance on one pin, minimum on the other.
(Might just be my maplins pots though)

Outside contacts are the 2 ends of the track, the middle one is the wiper (the bit that moves inside). As drawn turning clockwise will increase the resistance.

I'll add that a MM is pretty much inextricably linked to making a DIY laser though, you can get one for £7

All potentiometers are pretty much the same...
