This battle is different than when Angela fought ADAM. He will now stand in the center of the room and shoot lasers at you. The red ones are easy -- hide behind a wall. For the blue ones, you have to guess where it is going and get out of there. When defending yourself against ADAM in Phase 1, instead of hiding behind a pillar or dodging his blue attacks, hide behind the computer panels. When he attacks with his red ray, hide behind the pillars and he will not hurt you.
