Abstract
A saturable reactor is in a conductive state or has a magnetic switching function depending on the direction of the current flowing through it. Also provided is a power source apparatus for pulse laser utilizing the satiable reactor. The saturable reactor comprises a saturable magnetic core ( ); a principal coil ( ) wound around the saturable magnetic core ( ); a subsidiary coil ( ) wound around the saturable magnetic core ( ); and a power source ( ) which feeds electric current (ib) to the subsidiary coil ( ) when the transition of the saturable magnetic core ( ) from unsaturated state to saturated state is effected by the subsidiary coil ( ) wherein the saturable magnetic core ( ) becomes saturated state immediately when a current (i ) is applied to the principal coil ( ) in a direction same as the current flowing in the subsidiary magnetic coil ( ), while becoming the saturated state from an initial unsaturated state at the time when a product of the voltage and time reaches a predetermined value if a current (i ) is applied to the principal coil ( ) in a direction opposite to the current flowing in the subsidiary magnetic coil ( ).
