I just did something like that but i am not a potentiometer fan , I had time to kill anyways!!
I used a DDL design based on LM1086,
Using 4x 10-Ohm 5W Resistors, in parallel with a small switch soldered to the later 3 Resistors. Sounds Stupid ?! eH!
Well the design is funny, maybe not if u must need this kind of adjustable power laser..
1. 1x 10-Ohm + 3x Disconnected via Switch ~125mA
2. 2x 10-Ohm Connected & 2x Disconnected ~250mA
3. 3x 10-Ohm Connected & 1x Disconnected ~375mA
4. All Resistors Connected (Paralleled) ~450mA
That is not the best option there is, but i was planning ultra-ghetto 405nm build this time..
Had a fun time though !!!
