u/but_also_wtf

I own an nd:yag q-switch laser that has an alignment issue (or a hot spot in the beam that I am assuming is caused by that). In the photos, the two mirrors circled in blue were recently changed, with no adjustment to the housing they are in. (The can be removed and inserted without changing the angle or position of the casing). The photos after show the points I tested with zap it paper and how the beam looks currently.

I have some minimal experience and training with lens/mirror replacement, basic PM, etc but have not done an alignment. Unfortunately, where I live means flying in a tech from the US or another province for repairs. Is this something someone could walk me through or give their two cents on? Or do I just fly someone here.
