I could be that the shorted blue wire in some way injured your power supply. Does the mA meter slightly reduce in value when the power falls off ??
When a glass tube overheats the epoxy (I assume it is epoxy) bonding the rear mirror and output coupler will soften and allow small movement to take place. This affects the efficiency of the optical cavity and laser beam generation will suffer. In most instances it will return to it's original position when cold so check that you are not still overheating (no air bubbles and adequate flow rate etc etc ).
