Hello, in my playthrough I have just sided against the Institute and I have infiltrated their base. Now, I am about to head to the reactor, but before I do, wanted to make sure I got all the loot in the place. For the Astoundingly Awesome Tales #12 -Have Dog, Will Travel!, this is located inside the Institute and on the balcony of Holdren's quarters.

At this point, most of the doors in the Institute have the laser bars going across them and are inaccessible. Is it possible to shut down these laser bars so I can get the last magazine before completing the quest?

The doors with lasers I encountered had a nearby terminal that could be hacked which allowed me to turn off the lasers.

The doors I am trying to get into are up the spiral staircases. Were you able to get into those?

I had to reload a earlier save where I wasn't hostile with them just yet. I think that's your only option.
