An ozonizer has a flat plate-shaped low voltage electrode 7, a flat plate-shaped high voltage electrode 3 facing a main surface of the low voltage electrode 7. The ozonizer also has a flat plate-shaped dielectric 5 and a spacer for forming a discharge gap 6 of a thin thickness in a laminating direction provided between the low voltage electrode 7 and the electrode 3, an electrode cooling sheet 1 provided facing a main surface of the electrode 3 at a side opposite the discharge gap 6 for cooling the electrode 3. The ozonizer also has a thermal conducting/electric insulating sheet 2 sandwiched between the electrode 3 and the electrode cooling sheet 1. An alternating voltage is applied between the low voltage electrode 7 and the electrode 3 and a discharge is produced in the discharge gap 6 injected with oxygen gas to produce ozone gas.

摘要:
A silent discharge type pulse laser device having a pair of opposing electrodes, at least one of which is an electrode covered by a dielectric, which is mounted opposite to a metallic electrode with a silent discharge space in between, a laser resonator consisting of a total reflection mirror and a partial reflection mirror mounted opposite to each other with the silent discharge section in between, a source of high frequency voltage for supplying to the pair of electrodes a high frequency voltage having a predetermined period for silent discharge, and a controller for controlling the high frequency voltage from the source with respect to a first interval and a second interval that form a period longer than the period for silent discharge. The high frequency voltage is supplied to the silent discharge section at a first peak voltage value during the first interval and at a second peak voltage value during the second interval, wherein the second peak voltage value is sufficient to cause a discharge but insufficient to excite laser oscillation.
