Laser generating gas is different from cutting gas. Laser generating gas composition: N 2: The energy generated by the RF generator first excites N 2, causing it to be in a transition state.. CO 2: N 2 in the transition state will excite C0 2 which causes CO 2 to transition, and releases the laser.. He: Absorb CO 2 and excess energy, cool the system and turn it into heat.
