This disables the first barrier. Now, shoot your blue portal up onto the ledge where you started in the room. Walk to the box spawner and press the button. Now, grab the box and go through the orange portal.

Place the box so it cuts off the laser; that shuts off the second barrier. With that down, shoot your blue portal on the sky bridge above. This allows you a walkway to the exit door…but you’re not done yet.

After walking across the sky bridge and using the catapult to launch over to the other side, place a blue portal on the wall. Walk through it, press the box spawner button, and then take the box through. With the box on the other side of the glass, you’ll again place it so it cuts off the laser.
