Can I vary laser intensity? (DVD laser pointers and Potentiometers)?

Alright, I’m making a burning laser pointer and I have all the components for a driver and I also have a diode ready. BUT i was wondering if I could perhaps attach a potentiometer to the circuit possibly from the positive battery terminal to the LM317 to vary the laser’s intensity… I’d appreciate any info you could give me on attaching something of the sort. If you’d like to see the driver, then here’s the tutorial I’m using…
