PURPOSE:To facilitate a matching by a method wherein a DC power source which rectifies an AC to output a DC voltage, a high-frequency inverter for feeding a high-frequency power source to a laser tube and a matching circuit for making the impedances of the inverter and the laser tube match are directly coupled with an optical resonator part. CONSTITUTION:A DC power source 1, a high-frequency inverter 2 and a matching circuit 3 are arranged alongside one another on an optical resonator part 7 including a laser tube 5 and the distance between the circuit 3 and the resonator part 8 is made remarkedly shorter. When a device is constituted in such a way, a coaxial cable becomes unnecessary, there is no need to consider an impedance matching with the coaxial cable and the circuit 3 is also constituted simply and in low cost. If the device constituted in such a way is now mounted on the head of a laser processing machine, the point of the arm of a robot and so on, a simply constituted laser for exciting high-frequency discharge can be obtained. |
