Title: Power source for solid state laser
Inventor: KATSURAGI SEIICHI
IPC: H01S3/092
Filed: 1986-09-24
Abstract: PURPOSE:To eliminate a stepup transformer even if two or more lamps are used by connecting a plurality of solid state laser exciting lamps in parallel, providing current detectors to the respective lamps, and constructing a control circuit to avoid the firing of lamps on one side only. CONSTITUTION:A commercial power source is directly input to a DC power source 14 at the time of operation, rectified and smoothed by a rectifying and smoothing circuit 3. Here, when the commercial power source is AC 200 V, the maximum output voltage of the DC power source 14 is approx. DC 280 V. Accordingly, a tubular voltage per one lamp 5a or 5b must be 280 V or lower under necessary conditions. The lamps 5a, 5b are connected in parallel, and whether a current flows or not is decided by current detectors 6a, 6b and power source ON/OFF discriminators 12a, 12b connected thereto. Then, when one lamp is fired, a switching circuit 11 is opened by a one-side lamp discriminator 13 to stop supplying the output voltage of a reference power source 10 to a differential amplifier 9, the lamps 5a, 5b cannot maintain firing to be turned OFF.
