We observe the route from laser-off to laser-on in a CO<sub>2</sub> laser. On the route, on–off intermittency appears, which is caused by discharge instability near the laser threshold. By analyzing the probability distribution of a laminar phase near the onset of the intermittency, we confirm that what we have observed is on–off intermittency. We reproduce the intermittency through a numerical simulation of the laser rate equations.
