Title: Silent discharge type laser
Inventor: YAGI SHIGENORI
IPC: H01S3/097
Filed: 1981-05-11
Abstract: PURPOSE: To control laser output at high speed through silent discharge which changes high-frequency voltage applied between elctrodes or frequency.  
     CONSTITUTION: Voltage crest value applied between the electrodes and the discharge energy of one cycle have rectilinear relationship in silent discharge, discharge energy is injected intermittently at every one cycle, and stable discharge is kept. Accordingly, discharge power rectilinearly depends upon the voltage crest value, and is proportioned to line frequency. The discharge power has rectilinear relationship with the laser output. High-frequency voltage b applied at signal voltage a is amplitude-modulated for a period t 2 ∼t 3  and dropped, the quantity of discharge energy is decreased in response to the drop, and the laser output is reduced. The rise and fall of the laser output are steep, and output following the waveform of the signal voltage a is obtained. According to this costitution, high-speed cutting of characters, etc. can be executed to a metallic plate through programable control. Said cutting can be executed similarly even  when frequency is changed.
