High power CO₂ laser is widely used in various scientific, industrial and military applications. Vibration is a common phenomenon during laser working process, it will affect the working performance of high power CO₂ laser, vibration must be strictly controlled in the condition where the laser pointing is required. This paper proposed a method to investigate the vibration characteristic of high power CO₂ laser. An experiment device with vibration acceleration sensor was established to measure vibration signal of CO₂ laser, the measured vibration signal was mathematically treated using space-frequency conversion, and then the vibration characteristic of high power CO₂ laser can be obtained.
