Abstract
A laser includes an RF generator, a laser resonator and a cable connection provided between the RF generator and the laser resonator. The output impedance respective output and input impedances of two components directly connected by a cable of the cable connection are different. The cable impedance and length of the cable are selected such that the output impedance of an upstream one of the components is adjusted to the input impedance of the other of the two components. The two components may be any combination of the RF generator, laser resonator, and one or two matchboxes.
