Abstract

PURPOSE:To rapidly repsond to the output control signal in the variation of the output of the laser device by preparing a plurality of voltages of charging power source to charging and discharging capacitor becoming the power source of the exciting light source and selectively producing it via a semiconductor switching element. CONSTITUTION:Thyristors 21, 22, 23 are connected at the anodes to the output terminal of a DC power soruce 20 having output terminals of a plurality of voltages V1, V2, V3 being different, are connected at the cathodes commonly to through an inductance 27, a thyrsitor 28 and charging and discharging capacitor 29 of a serial resonance circuit. A light source 30 for exciting laser substance is connected across the capacitor 29. The gate terminals of the thyristors 21, 22, 23 are connected to an output control circuit 24, which selectively conducts a required thyristor on the basis of the output control signal Cp to thus cause the capacitor 29 to be charged at the required voltage of the DC power source 20, thereby rapidly controlling the emitted light output of the light source 30.
