Magnetically induced pulser laser excitation system
An apparatus is described for exciting a laser having first and second electrodes and containing a gas mixture comprising: preionization means for preionizing the gas mixture, primary energy storage means for storing a sufficient electrical energy for the operation of the laser. Energy transfer means connects the primary energy storage means and the first electrode in an impedance matching manner for transferring the sufficient electrical energy the form of a main discharge voltage pulse, trigger pulse generating means forms a part of the primary energy storage means and for generating a trigger pulse in response to the main discharge voltage pulse. Secondary energy storage means stores an electrical energy, electromagnetic energy transfers means connected between the secondary energy storage means and the second electrode for transferring electromagnetically the electrical energy in the form of a high voltage pulse which breaks down the gas mixture. Switching means connects to the electromagnetic energy transfer means for initiating the electromagnetic energy transfer in response to the trigger pulse. The main discharge voltage pulse is longer in duration than the high voltage pulse. The two pulses are coincidental for a period of time to produce gas breakdown in the laser and to permit the energy transfer means for sufficient energy from the primary energy storage means to the laser.
