Combining beams with knife-edge mirrors?

I have 4 Melles Griot 5mw HeNe tubes that I would like to combine using some 2 PBS cubes (which I already have) and a "knife-edge" mirror.

Could anyone recommend a source for the appropriate mirror, and perhaps a sketch on how to utilize the mirror to combine beams?

(this is just an experimental side project, so I would like to pursue this without spending much $$....)

Thanks!

HeNe is a very wacky laser. Polarization depends on how worm the laser is:cool:

are there a P in th model number?

I appear to have (3) model #'s "05-LHR-99",
and (1) model # "1101P-0249".

Any suggestions for combining into a single beam would be appreciated!

(especially if it won't cost much - these were free, late 80's models :D)

0-5lhr are non polarized and the 1101p is polarized. this leaves you to grazing incidence near miss combining.

SO, knife-edge mirrors only, I guess!
Any recommendations on sources?
