Laser pumping by PFN power source.
The use of a pulse forming network (PEN) as a main discharge power supply was tested in a electron-beam-controlled CO(2) laser amplifier in order to improve the utility efficiency of the energy in storage capacitors. The impedance of the pumping discharge through the laser gas was controlled by the accelerating voltage of the electron beam to match the PFN line impedance. In the matched condition all of the stored energy in the PFN was transffered to the laser gas at a constant electric field strength which was optimum for laser pumping.
