Abstract
A laser structure utilizes air cooling and RF induction excitation of a gaseous active medium. A means for exciting the active medium is provided including a switching power supply utilizing pulse width modulated switching to provide an RF energy output. The RF output is coupled to a tank circuit which comprises a capacitor, an inductor, and at least one coupling structure. A means for generating a magnetic field-along the axial length of the laser bore is provided and can comprise either permanent magnets or a DC source coupled to the coupling structure. The laser further includes means for dissipating heat from the laser bore by utilizing the coupling structures as convective cooling fins with forced air circulated thereabout.
