FIG. 1.

Schematic diagram of laser system. C p, C s, and C b represent primary, secondary, and buffer capacitors, respectively. Capacitor-transfer circuit is formed by turning SW on, and direct-drive circuit is formed by turning SW off.

FIG. 2.

Dependence of laser output energy and breakdown voltage on N2 pressure in discharge tube with an inner diameter of 4 mm and a length of 10 cm, at a primary capacitance of 4.4 μF and a secondary capacitance of 700 pF. Black circles and white squares represent laser output energy and breakdown voltage, and vertical axes are indicated by black and white arrows, respectively. Error bars indicate standard deviation. (a) Capacitor-transfer circuit with a buffer capacitance of 400 pF. (b) Direct-drive circuit.
