Title: Controlling apparatus for co2 gas laser
Inventor: HOSOKAWA TOMIAKI
IPC: H01S3/104
Filed: 1989-10-06
Abstract: PURPOSE:To prevent an overshoot and a damping at a rise by a method wherein, at a rise of a high-frequency output waveform, an output of a waveform setting circuit is input to a delay circuit from an output of a power setting circuit and a feedback control operation is started at a delayed stage. CONSTITUTION:While, at a rise of a waveform, an output of a waveform setting circuit 33 is counting a delay time in a delay circuit 39, an output value of a power setting circuit 35 is input to an attenuation circuit 25; a high-frequency output rises by an open-loop control operation. When the circuit 39 executes a counting-up operation, switches 40, 41 of a changeover circuit 36 are closed by its output; an output of a power detection circuit 30 and an output of the circuit 35 are compared and amplified by an error amplification circuit 37; a feedback control operation is started at a delayed stage. Thereby, an overshoot and a damping at a rise of a high-frequency output waveform are not caused; a peak ripple value in a stationary state after the rise of the waveform can be made small.
