ABSTRACT:
A laser designed to emit a pulsed beam of short wavelength comprises two bodies of nonconductive material within a cylindrical housing, at least one of these bodies being a flat ceramic disk with a high dielectric constant. A narrow interspace between the two bodies is occupied by two coplanar metal layers with confronting rectilinear edges forming an elongate excitation cavity between them, these layers being galvanically interconnected through an inductance and constituting a pair of capacitors with a common metal layer on the opposite face of the ceramic disk. One of the coplanar layers is connected to a source of high potential, the other of these layers being intermittently energizable by a generator of trigger pulses to excite a gas filling the elongate cavity.
