The embodiment of the invention provides a gas control method of a laser and the laser. In the embodiment of the invention, in the process that the laser normally discharges to emit light, the light emitting voltage of the laser and the discharge energy variation of the laser are acquired; and determining whether to inject the working gas in the cavity of the laser according to the light output voltage and/or the discharge energy variation. Therefore, gas supplementation of the laser is controlled by determining whether gas injection is carried out or not, so that the laser can discharge in a relatively stable state for a long time, and the discharge time is delayed. The laser can maintain stable performance for a long time, the production efficiency is improved, and the cost is saved.
