Electrophoresis pulse metal steam laser system

Abstract

The invention discloses an electrophoresis pulse metal vapor laser system, comprising a laser discharge tube, a pulse discharge circuit, a temperature controller and a gas-flow rate control system. A laser medium is positioned inside a storing side pipe close to the anode; the optimal metal vapor density necessary to the generation of laser can be controlled independently by adjusting the temperature of a heater outside the side pipe; the even distribution of the metal vapor density at a discharge active region and the efficiency and stable operation of the laser can be realized by the electrophoresis effect of the high-frequency pulse electric field and the pliant flow way of gases. The system has the advantages that the discharge is stable, a light path and a discharge channel are not blocked and the necessary optimal metal vapor density can be kept for a long time. The system has been applicable to the electrophoresis He-Sr <+> (Ca <+>) laser system successfully and the recombination laser with close watt power and the long-time stable operation of the self-terminating laser are obtained.

Description

technical field [0001] The invention relates to a laser, in particular to an electrophoretic pulsed metal vapor laser system. Background technique [0002] Pulsed metal vapor laser is an important branch in the field of lasers. It has the characteristics of rich spectral lines (from ultraviolet to infrared), multiple excitation mechanisms, and high output power and efficiency. It is widely used in medical, entertainment, material processing, Precision machining and scientific research and other fields. The traditional metal vapor laser generally uses a discharge tube with a casing or a spacer ring structure. The laser medium (metal or metal compound) is placed on the inner wall of the discharge tube at equal intervals, and the vapor density required to generate the laser is obtained by self-heating of the discharge. The disadvantage is that the change of the input electric power and the random discharge of the metal medium lead to the change of the metal vapor density and t...

Problems solved by technology

The traditional metal vapor laser generally uses a discharge tube with a sleeve or spacer structure, and places the laser medium (metal or metal compound) on the inner wall of the discharge tube at equal intervals, and obtains the vapor density required for laser generation through self-heating of the discharge. The disadvantage is that the change of the input electric power and the random discharge to the metal medium during discharge lead to the change of the density of the metal vapor and the instability of the discharge, especially for the small-caliber and highly active alkaline-earth metal vapor laser, the optical path is often partially blocked And laser medium is consumed quickly, which affects the working efficiency, stability and output characteristics of the laser
