noob question alert!

New to diodes (old school gas geezer here)

2 of these, with a pbs, should be no issue, right? I assume I'd correct the optics PRE-pbs?

If so, if its as easy as it sounds to have 2 of these to make a nice 1w setup, can you up my order from 1 to 2? Thanks!

These broad stripe diodes lend themselves to knife edging two or more together before correction optics. You can then knife some more together and pbs the two groups

haha, ok, so lets assume that I only plan on using 2. Why knife edge over pbs?

You do not need a PBS at all.

you can do 2 options:

1. correct the fast axis with a prism and shoot it in a pbs. this way you need 2 prism pairs and a PBS.

2. Knife edge 2 diodes together and correct them with a prism pair . this way you only need 1 prism pair and no PBS.

If in the future you need to double the power you could do this again and then combine it with a pbs.

You choose the best solution.
