Eric, the barlowed laser method will work with any laser that inserts in the focuser. You need a screen (paper sheet) at the end of the barlow, onto which the mirror projects an image of its centre spot. The screen should have a hole in the centre for the laser light to pass through. You align the mirror centre spot's image on the screen with the hole in the screen by adjusting primary mirror collimation screws.
Sorry if I'm not explaining it properly. It's easier to show than describe.
