The easiest alignment method 'from scratch' that I can think of would likely be a similar process as i've used on badly misaligned argon-ion's before. Which is set up a fixed jig and use a second laser like a low power HeNe shining through the cavity through a piece of paper with a small hole in it.. and using the resulting reflections off each surface as a reference to get each component roughly parallel to the alignment beam. I know with argon-ions, this would get the mirrors close enough to have a beam again, then you just tweak for best output.. So i'd think it'd probably work for a DPSS as well.
