| titleOfInvention | Sputtered vapor laser |
| abstract | A sputtered vapor laser which features two discharges within a single lasing apparatus. A secondary discharge is caused to occur between an anode and a hollow cathode whose surface is coated with a suitable lasing material. The sputtering action of the secondary discharge on the surface of the hollow cathode produces vapor of the lasing material inside the hollow cathode. The electric field set up by the cathode of the primary laser discharge acts to draw the vapor of the lasing material towards the primary cathode along the main plasma section of the laser to provide the required concentration of atoms in which to sustain laser oscillation. The atoms of the sputtered vapor are excited in the main plasma section by inelastic collisions with excited carrier gas atoms or ions or with electrons energized by the electric field existing in the discharge between the hollow cathode and the primary cathode. The hollow cathode is biased more positively than the primary cathode so that it acts as the anode of the primary laser discharge. Electrical feedback can be utilized between the primary and the secondary discharge circuitry to control the current of the secondary discharge. |
