An ideal laser power supply should bring a capacitive storage medium to a programmable voltage level at a constant rate. This voltage level must be maintained until the laser is fired, at which time the charging source must be immune to severe transients. Considerations include efficiency, size, cost, and reliability. A switched mode charging source is described which has been in commercial production for several years, and which will transfer 5KW of average power to a value of capacitance ranging from 20 to 100nF at approximately 32KV with repetition rates to 500Hz.
