PURPOSE:To always cut stably a work by dividing in frequency an oscillating frequency output oscillated from an oscillator by selecting means, controlling the output of Q switch, and altering the laser output. CONSTITUTION:The reference oscillation output of an oscillator 54 is divided in frequency by frequency dividers 56-66, and input to one terminals of AND gates 70-80. Bit signals I1-I3 regarding speeds are fed from a robot to terminals A1-A3, and signals (a)-(f) are output from a decoder 36 through NADN gates 30a-30c and OR gates 34a-34c to AND gates 70-80. For example, the AND gate 76 is opened by an a output, and the NAND gate 42 is opened for a delay time determined by a delay circuit 44 through an OR gate 40 by an output signal A. Then, the gate 46 is opened by a signal from signals I1-I3 from the gate 38, led as an output through the gate 48 and inverters 50, 52 to a controller 53 to energize a Q switch, thereby obtaining a laser output corresponding to a frequency. |
