Multipoint Uniform Ring Electrodes for Cylindrical Inert Gas Discharge Lamps

Abstract

The invention discloses a multipoint uniformly-distributed annular electrode for a cylindrical inert gas discharge lamp. The annular electrode comprises an annular electrode disc, the first end face of the annular electrode disc is evenly provided with a plurality of discharge end points, and the outer side face or the second end face of the annular electrode disc is provided with a power supply connection end. The second end face is arranged opposite to the first end face. According to the annular electrode, a structure that the discharge end points are evenly fixed on the annular electrode disc is used, so that efficient light emitting of a pumping lamp can be achieved, and the utilization rate of the pumping light is improved.

Description

technical field [0001] The invention relates to the technical field of high-power lasers in the technical field of lasers, in particular to a multi-point uniformly distributed annular electrode used in a cylindrical inert gas discharge lamp. Among them, the lamp pumping technology is one of the main technologies of the laser, and its pumping effect is closely related to the pumping lamp. Background technique [0002] The existing solid-state laser pumping mainly adopts arc lamp pumping and diode laser pumping. Among them, arc lamp pumping has poor pumping uniformity, large transmission loss of pumping light, low pumping efficiency, and heat loss. The efficiency of laser replacement is low; the pumping efficiency of diode lasers is higher than that of arc lamps, but due to the particularity of the pumping structure of diode lasers, the pumping uniformity is poor, and the cost of high-power lasers is high.

[0002] The existing solid-state laser pumping mainly adopts arc lamp pumping and diode laser pumping. Among them, arc lamp pumping has poor pumping uniformity, large transmission loss of pumping light, low pumping efficiency, and heat loss. Large, low laser replacement efficiency; diode laser pumping efficiency is higher than arc lamps, but due to the particularity of diode laser pumping structure, pumping uniformity is poor, and the cost of high-power lasers is high

[0003] The existing inert gas discharge lamps are all in the shape of straight rods, the electrodes are distributed at both ends, and the electrodes are not ring-shaped, which makes the light energy utilization rate low
