Abstract
A process and apparatus for increasing the pulse repetition frequency in a laser is disclosed. The laser includes first and second series connected discharge tubes, a supply unit for applying energy to the discharge tubes and a pulse generator for controlling the discharge of the discharge tubes. The discharge tubes are alternately discharged such that one of the tubes is charging as the other of the tubes is discharging. In this manner, the maximum pulse frequency of the laser is twice the maximum pulse repetition frequency of each of the individual discharge tubes.
Claims6
A process for increasing the pulse repetition frequency of a laser of the type including first and second series connected discharge tubes, a supply unit for supplying energy to said discharge tubes and a pulse generator for controlling the discharge of said discharge tubes, said process comprising the steps of:
- alternately discharging each of said discharge tubes;
- charging one of said first and second discharge tubes while the remaining said discharge tube is discharging.
Laser apparatus, comprising:
- (A) first and second series connected discharge tubes;
- (B) a supply unit for supplying energy to said discharge tubes;
- (C) pulse generator means for controlling the discharge of said discharge tubes, said pulse generator means to discharge said tubes in such a manner that:
- (1) said first and second discharge tubes are alternately discharged;
- and
- (2) each of said discharge tubes is being charged while the other of said discharge tubes is being discharged.
