摘要： Disclosed herein is a method for obtaining oscillation in krypton ion gas laser, wherein such oscillation is not subject to the phenomenon of instability which method is carried out by causing laser oscillation with high discharge current density in a capillary discharge tube filled with a discharge gas consisting principally of krypton, at a pressure which exceeds a predetermined value related to the discharge current density.

摘要： A plurality of capillary discharge tubes are interconnected in serial alignment with orientations such that the mutually nearest electrodes of adjacent discharge tubes are of the same polarity to form a single long discharge tube to thereby eliminate cataphoresis or electrophoresis of the discharge gas occurring within this tube during gaseous discharging operation thereof.

摘要： 1,271,425. Lasers. HITACHI SEISAKUSHO K.K. 19 June, 1969 [21 June, 1968], No. 31168/69. Heading H1C. In a gas laser, two ceramic capillary tubes 2A, 2B, Fig. 1, are serially and coaxially disposed in a common envelope 1A, and each has a pair of electrodes between which current may be passed for pumping. The electrodes shown between the tubes at 1 are of the same polarity, opposite to that of electrodes 8A, 8B. Each tube is water cooled, and has a jacket comprising members 3, 4, 5 and 6, the rings 5 being flexible and members 3 and 4 being flexibly connected to prevent stress damage to the tubes. Pressure equalization by-passes 7A, 7B are provided. Energy extraction is via windows 10A, 10B disposed at the Brewster angle and spaced from electrodes 8A, 8B to minimize contamination of the windows by cathode sputtering. Three or more capillary tubes may be similarly used. A magnetic field may be impressed along the common tube axis, to enhance output. In Fig. 2, the cathodes 16A, 16B, and anodes 12A, 12B are water cooled, and the by-passes 14A, 14B are wound around the capillary tubes. Water jackets 13A, 13B are provided around the tubes and each tube has a solenoid 17A or 17B for impressing a magnetic field, for example of 300 gauss. Any even number of tubes may be joined in this structure, adjacent electrodes being of the same polarity. In both Figs. I and 2 the gaseous active medium fills the envelope, and may be krypton or argon.

摘要： 1,263,500. Lasers. HITACHI SEISAKUSHO K.K. 19 June, 1969 [21 June, 1968], No. 31169/69. Heading H1C. In a krypton laser pumped by an electric discharge within a capillary tube containing the active medium, termination of laser output by the pinch effect is prevented by operating the discharge under conditions of pressure and current which lie above the line plotted in the figure. A minimum current of 500 A/cm. 2 is required, and a magnetic field of 600-1200 gauss may be applied along the tube axis to enhance output. The use of such a magnetic field increases the slope of the plotted line, so that a higher gas pressure is required for stable operation at a given current. The maximum pressure used should be restricted to three times that given by the plotted line to avoid undue loss of output. Argon, neon and helium may be used with the krypton, the total pressure of the gases being that determined from the figure. Without the magnetic field, the initial pressure P (torr) is given by P # 1À2 x 10 -3 j, where j is the current density (amps/cm. 2 ). With the field, P # 1À9 x 10 -3 j.
