Implication

Experimental study demonstrates high-efficiency energy extraction in a fast-discharge krypton fluoride laser, indicating the viability of low-impedance water dielectric Blumlein drivers.

Key Points

Develop and evaluate a fast-discharge krypton fluoride (KrF) excimer laser powered by a low-impedance water dielectric Blumlein pulse forming network.
Constructed a low-impedance water dielectric Blumlein pulse forming network (PFN) with an integral multi-arc-channel initiation switch.
Integrated behind-the-cathode ultraviolet arc preionization driven by an integral low-inductance water capacitor across a 70-cm³ extraction volume.
Evaluated laser energy output and discharge homogeneity at PFN impedances of 1.3 Ω and 0.6 Ω.
Generated 180 mJ per pulse at a laser efficiency of 1.2% from a 70-cm³ volume using a 1.3-Ω PFN impedance.
Obtained 250 mJ per pulse under similar discharge conditions when utilizing a 0.6-Ω PFN impedance.
Achieved an extremely homogeneous electrical discharge in both configurations as a result of uniform ultraviolet preionization.
