SCHEME OF EXCITATION OF LASERS ON METAL FUME Russian patent published in 2006 - IPC H01S3/97 H02M7/5375 H03K3/57 H01S3/227 

FIELD: the invention refers to laser technique.

SUBSTANCE: the scheme has n modules linked up to a power source through a charging inductance. Each module has one section of a multisectional high frequency transformer. Each section of the transformer has two primary windings coiled back-to-back and one secondary winding. Each module has also two accumulative condensers, two charging diodes and twp transistor commutators. The accumulative condenser is charged through a corresponding charging diode and a charging inductance from the power source and is discharged through corresponding transistor commutators and primary windings of the section of the multisectional transformer. The shutters of the transistor commutators are linked up through devices matching with the scheme of the starting. The secondary windings of all sections of the multisectional transformer are successively connected and linked up to the outputs of the gas discharge tube.

EFFECT: increases reliability of the scheme of excitation due to using of low voltage elements.
