The laser consists of a metal housing (23) inside which there are two parallelepipedic dielectric blocks (7 and 10) made of a material of high dielectric coefficient, the blocs forming two capacitors (C<u1>u and C<u2>u) in conjunction with the housing's bottom (23) and two metallic armatures (11 and 12). The armature (11) common to both blocs (7 and 10) has a longitudinal rim (1) alongside bloc (10) towards a longitudinal rib (2) pointing from the bottom of the housing (23), the space (5) thus delimited between the rim (1) and the rib (2) constituting the laser cavity occupied by the active gas medium. As the armature (11) is connected to the housing (23) through a charging resistance (9), a high voltage source (18) connected between the other armature (12) and the housing (23) ensures the charge of one of the capacitors (C<u1>u). The production of a stimulated emission (26) inside the laser cavity (5) is initiated by the discharge of a spark-gap (E) disposed between the armature (12) and the housing (23), which discharge has effect to entail a transfer of charge from capacitor (C<u1>u) to capacitor (C<u2>u) connected to the laser cavity (5), which thus provokes the electric excitation of this cavity (5). |
