Middle power carbon dioxide laser tube

Abstract

The invention discloses a medium-power CO2 laser tube, its main character: the discharging tube and water cooled tube are placed in a large gas storage tube, two ends of which is sintered with the water cooled tube, there are at least two groups of discharging tubes and water cooled tubes, the end parts and tail parts between components are sinter into a serial light path in II, V or W shape, each discharging tube is opened to the large gas storage tube through a back gas tube connected with, the former discharging tube's initial end is set with a full reflector and the latter discharging tube end is set with an output coupling mirror, all the head and tail sintered ends of the two discharging tubes are set with full-reflecting refractors and all the inner electrodes of the two discharging tubes are connected with DC power supply. Its bulk is small and it is light and not influenced by temperature variation, the output power and facular mode are stable and it adopts DC power supply to excite in sections, effectively reducing exciting voltage and enlarging the control range of power and can be widely applied to 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 are no practical products that satisfy users. In order to obtain medium power laser output, one of the current domestic solutions 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, "П"-shaped or "v"+"П"-shaped folded optical path structure, and then use mechanical methods to Fix it, check the Chinese patent announcement number is CN2190358Y, the name is "truss-type quartz folded gas laser" which adopts this structure, and its main claim is descri...

Problems solved by technology

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

In order to solve this situation, a radio frequency (RF) excitation technology is adopted abroad to make a slab-shaped laser. The laser made according to this technology is small in size, light in weight, long in life, and noiseless, but it is expensive. Difficult to widely promote and apply in our country
