Abstract

To provide high efficient pumping source for THz laser, we designed a new active frequency stabilized system for gain switched RF CO₂ laser. According to our theoretical analysis and experimental study, the pulse setup time is varied for different output power. The pulse setup time is shortest when the output power is highest for a pulse laser. It is equivalent to stabilize the laser frequency and power if the pulse setup time is locked in the center of laser gain curve. By the method of adjusting the pulse setup time, we have stabilized a pulse rf excited CO₂ laser at the center of the laser gain curve. The frequency stability is estimated to be less than 5MHz.
