Title: Laser excitation device
Inventor: KOMATSU JUSAKU
IPC: H01S3/0971
Filed: 1987-09-28
Abstract: PURPOSE:To execute an electric discharge of a large electric power laser tube even by using a switching element whose electric power capacity is small by a method wherein tow or more charging and discharging circuits composed of a diode for counterflow prevention use, a capacitor for discharging use and the switching element are connected in parallel with the laser tube. CONSTITUTION:When an electric power capacity required to excite a laser tube 3 is not sufficient with one switching element, required electric power can be supplied to the laser tube 3 if a charging and discharging circuit containing two or more switching elements is added. A signal to be input to switching element drive circuits 17-19 is adjusted timely by using an appropriate delay circuit. In this case, an inductance of the charging and discharging circuit as viewed from the laser tube 3 is lowered because two or more charging and discharging circuits are connected in parallel. Accordingly, an electronic discharge of the laser tube can be obtained in a short time. Diodes 8-10 for counterflow prevention use can prevent any erroneously conductive switching element from being broken down because an electric charge accumulated in a capacitor for discharging use is blocked by the diodes and does not flow even when the switching elements in other charging and discharging circuits become erroneously conductive.

Inventor: TAKAHASHI NORIO
IPC: H01S3/097
Filed: 1985-10-31
Abstract: PURPOSE:To enable the discharge current of a laser tube 5 to be maintained constant even if the power supply voltage varies, by maintaining the current flowing through a Zener diode for reference power supply constant by a comparing amplifier, thereby making the Zener diode output voltage constant. CONSTITUTION:If the voltage across power supply terminals 13, 14 rises and the current Iz flowing through a Zener diode 12 is going to increase, the detected voltage by a resistor 19 rises, the output voltage of a compare amplifier 15 falls, causing the current Iz flowing through the Zener diode 12 to decrease, and if the input voltage falls, the current Iz is caused to increase. Therefore, the current flowing through the Zener diode 12 is controlled to be constant by the compare amplifier 15, and the output voltage Vs of the Zener diode 12 is also maintained constant. Further, since a comparing amplifier 10 compares and amplifies Vs and a current detecting voltage Vo to control a switching circuit 1, the discharge current between the anode 6 and the cathode 7 of a laser tube 5 is also maintained constant.
