Middle power carbon dioxide laser tube

Abstract

The invention discloses a medium-power carbon dioxide laser tube, which is mainly characterized in that the discharge tube (4) and the water-cooled tube (6) are placed in a large gas storage tube (5), and the two ends of the large gas storage tube are connected to the Water-cooled tube burning, the discharge tube and water-cooling tube components placed in the large gas storage tube are provided with at least two groups, and the ends and tails of each component are burnt to each other to form a Π shape, a V shape, a Z shape, or a W shape. Shaped series optical path, each of the discharge tubes communicates with the large gas storage tube through the gas return tube (2), the initial end of the first discharge tube is provided with a total reflection mirror (9), and the end of the last discharge tube is provided with an output A coupling mirror (7), and a total reflection turning mirror (1) is provided at the head and tail burn-in ports of each discharge tube, and the inner electrodes of each discharge tube are respectively electrically connected to a DC power supply. The design of the present invention is successful, its volume is small, its weight is light, it is not affected by temperature changes, its output power and light spot mode are stable, and it adopts DC power supply segmental excitation, effectively reduces the excitation voltage, increases the control range of output power, and can be widely used Used in laser processing industry.

Description

【Technical field】 [0001] The present invention relates to the invention of a laser tube, in particular to a medium-power carbon dioxide laser tube, and in particular to a laser tube used in the laser processing industry. 【Background technique】 [0002] At present, the market potential of medium-power (hundreds of watts to kilowatts) lasers is huge, but up to now, there is no practical product that satisfies users. In order to obtain medium-power laser output, a current domestic solution is to lengthen the discharge area. Because the discharge area is too long, the excitation voltage is high and the transportation is inconvenient. The second solution is to use a "V"-shaped, "II"-shaped or "v"+"II"-shaped folded optical path structure, and then mechanically dissipate it. Fix it, check the Chinese patent notification number as CN2190358Y, and the name "truss-type folded quartz gas laser" adopts this structure, and its main claim is described as "a trus...

Problems solved by technology

Another solution is to use fast-flowing gas excitation to make a cross-flow or axial laser. The result is bulky, heavy, serious noise pollution, large gas consumption, and high operating costs.

In order to solve this situation, foreign countries have adopted a radio frequency (RF) excitation technology to make slabs to form lasers. The lasers made according to this technology are small in size, light in weight, long in life, and noiseless, but they are expensive. Difficult to widely promote and apply in our country
