A rf excitation system that can drive a gas laser constructed of multi
ple wide, but narrow-gap (slab), discharge volumes is presented. Reson
ant cavity techniques adopted from microwave applications are employed
to provide uniform rf power division and impedance matching into each
electrode channel. This approach when applied to a large radial array
of gain channels can be used to create a very high-power laser system
in an unusually compact package. (C) 1995 American Institute of Physi
