A new feedback controlled current stabilized power supply for gas laser
Abstract
A feedback controlled current stabilized power supply for CO2, wave guide lasers is reported. This current negative feedback control method involved connecting the control transistor to the DC output and of an AC bridge rectifier. Current is stabilized in the range of 2 to approximately 4 mW, the unstability of the current is less than 1% with respect to 20% fluctuation of network voltage. The principal circuit and the voltage-current wave forms of the power supply are shown.
