[0001] The utility model relates to a carbon dioxide glass tube laser, especially a carbon dioxide glass tube laser with positive and negative electrodes emitting light simultaneously. BACKGROUND

[0002] Most of the current carbon dioxide glass tube lasers adopt a typical sealed structure, in which the resonant cavity generating laser light is composed of two parallel mirrors. A common carbon dioxide glass tube laser adopts a mirror with high reflectivity and an output mirror with low reflectivity to form the resonant cavity structure. The laser is excited to oscillate in the resonant cavity and then output from the output mirror with low reflectivity. However, this composition of the resonant cavity mirror can only output from one end.

[0003] Nowadays, with the development of production, the market demand for laser processing is increasing.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Example 1

[0020] like Figures 1 to 3 As shown, a carbon dioxide glass tube laser capable of emitting light simultaneously from both positive and negative electrodes includes a glass tube 1. A first metal head 2 is attached to the outside of the positive end flange of the glass tube 1, and a first electrode 6 is installed inside the metal head 2. A first output mirror 4 is provided inside the metal head 2, and a first heat sink 5 is connected to its outside. A second metal head 7 is attached to the outside of the negative end flange of the glass tube 1, and a second electrode 11 is installed inside the metal head 7. A second output mirror 9 is provided inside the metal head 7, and a second heat sink 10 is connected to its outside.

[0021] The first metal head 2 has an electrode wire connection hole A2-1 on its circumference. The electrode wire connection hole A2-1 is threadedly connected to the first terminal bolt 3. The first metal head 2 has a laser channel A2-2 inside. The front end of the laser channel A2-2 has a step A2-3. The first output mirror 4 is attached inside the step A2-3 and is concentrically arranged with the laser channel A2-2. The first metal head 2 has an external thread A2-4 on its outer side. The first heat sink 5 is installed on the outer side of the external thread A2-4. The first heat sink 5 has an internal thread A5-1. The internal thread A5-1 mates with the external thread A2-4. The first heat sink 5 is threadedly connected to the first metal head 2. The first heat sink 5 has two or more annular heat dissipation grooves A5-2. The first heat sink 5 has a laser channel B5-3 inside. The laser channel B5-3 is concentrically arranged with the first output mirror 4 and the laser channel A2-2.

[0022] The second metal head 7 has an electrode wire connection hole B7-1 on its circumference, which is threaded to the second terminal bolt 8. A laser channel C7-2 is located inside the second metal head 7, with a step B7-3 at the front end of the laser channel C7-2. The second output mirror 9 is attached to the step B7-3 and is concentrically positioned with the laser channel C7-2. An external thread B7-4 is located on the outside of the second metal head 7, and a second heat sink 10 is installed on the outside of the external thread B7-4. The second heat sink 10 has an internal thread B10-1, which mates with the external thread B7-4. The second heat sink 10 is threadedly connected to the second metal head 7. The second heat sink 10 has two or more annular heat dissipation grooves B10-2. A laser channel D10-3 is located inside the second heat sink 10, and is concentrically positioned with the second output mirror 9 and the laser channel C7-2.

[0023] Working Process: A first output mirror 4 is installed at the positive end of glass tube 1 of the CO2 glass tube laser, and a second output mirror 9 is installed at the negative end. The high-voltage line of the laser power supply is connected to the first terminal bolt 3 and the second terminal bolt 8 of the positive and negative terminals of the CO2 glass tube laser, respectively. The DC power supply voltage is applied to the first electrode 6 and the second electrode 11 of the positive and negative terminals of the CO2 glass tube laser. The working medium (mainly CO2, N2, and He) in the discharge tube of the CO2 glass tube laser is excited to a high energy level, resulting in population inversion. When incident photons enter the laser, they excite atoms or molecules at high energy levels to undergo stimulated emission, producing photons identical to the incident photons. These photons are continuously reflected and amplified in the optical resonant cavity, eventually forming a high-intensity coherent beam of light, i.e., laser light. Since the reflectivity of both the first output mirror 4 and the second output mirror 9 is low, the laser light can be output simultaneously through both output mirrors, thus realizing simultaneous light output from the positive and negative terminals of the CO2 glass tube laser.

[0024] When the first output mirror 4 and the second output mirror 9 with different transmittances are selected at both ends of the carbon dioxide glass tube laser, the two ends of the laser output lasers of different wavelengths. This satisfies the fact that different processing materials have different absorption rates of carbon dioxide lasers with wavelengths of 9.3μm and 10.6μm. Therefore, the laser processing equipment can output lasers of the corresponding wavelengths according to different processing materials.
