A silent discharge type laser device is described including a pair of discharging electrodes at least one of which is coated with dielectric material, a laser gas medium between the electrodes, a power source for applying an AC voltage between the discharge electrodes to cause silent discharging therebetween, and an optical resonator having a totally-reflective mirror and a semi-transparent mirror which mirrors delimit a discharging space in a relation opposed to each other, wherein the silent discharging is used to promote laser oscillation. The laser device is characterized by: means for setting a target value or electric charge passed between the discharging electrodes; means for detecting the amount of electric charge passed between the discharging electrodes; and means for controlling output of the power source in response to the detected value of the electric charge-amount detecting means to equalize the target value and the detected electric charge-amount thereby establishing a constant laser output.
