Paper Abstract

Pre-charging of peaking capacitors has been tested on a high-repetition-rate transversely excited atmospheric CO2 laser. The peaking capacitors, connected to the discharge electrodes, were divided into two blocks in series. One part was pre-charged by a DC voltage source and another part was pulse-charged. An efficiency of over 6% was obtained by only 7 kV pulse voltage, and was higher than that obtained in a charge-transfer-type circuit. A high repetition rate operation up to 1 kHz was demonstrated.
