Description

Technical Field

[0001] The utility model belongs to the technical field of lasers, and particularly relates to a radio frequency CO2 laser with a coaxial red light device. Background Art

[0002] Carbon dioxide laser is a type of laser, which can be called "invisible". The wavelength of the laser it emits is 10.6 microns, and its "body" is in the infrared region, which cannot be detected by the naked eye. It has two working modes: continuous and pulsed. It is used for laser cutting, welding, drilling and surface treatment. The laser power generated by the continuous mode can reach more than 20 kilowatts. The laser with a wavelength of 10.6 microns generated by the pulsed mode is also the most powerful laser.

[0003] Since carbon dioxide lasers are invisible, when lasers on the market need to work with red light, they can only be installed separately at a location that is not coaxial with the laser emitted by the carbon dioxide laser, and the position and angle need to be adjusted to achieve the best coaxial effect. At the same time, various factors such as installation space must also be considered, and the operation process is relatively complicated. Utility Model Content

[0004] In order to solve the technical problems that the laser in the current market can only be installed separately at a position that is not coaxial with the laser emitted by the carbon dioxide laser when it needs to work with red light, and the position and angle need to be adjusted to achieve the best coaxial effect, and various factors such as installation space must also be considered, and the operation process is relatively complicated, the utility model provides the following technical solutions:

[0005] The utility model relates to a radio frequency CO2 laser with a coaxial red light device, comprising a laser optical resonant cavity, a radio frequency excitation power supply is fixedly installed on the top of the laser optical resonant cavity, an aurora mirror end is arranged at one end of the laser optical resonant cavity and a light output mirror end is arranged at the other end, and a heat dissipation component and a red light component are arranged on the laser optical resonant cavity;

[0006] The red light component includes a beam combining mirror seat, a red light adjustment seat and a red light head. The beam combining mirror seat is integrated and installed at the light output mirror end of the laser optical resonant cavity. The beam combining mirror seat is provided with a mounting column head corresponding to the light output mirror end. The beam combining mirror is fixedly installed on the mounting column head. The red light adjustment seat is fixedly installed on the outer end of the beam combining mirror seat. The side end of the red light adjustment seat is provided with three pin holes and the red light head is fixedly installed on the inner end wall of the red light adjustment seat through the pin holes. The red light adjustment seat is provided with multiple adjustment holes.

[0007] As a preferred technical solution of the utility model, the end of the radio frequency excitation power supply close to the aurora mirror is provided with a signal interface and a first power supply interface.

[0008] As a preferred technical solution of the utility model, the heat dissipation assembly includes a heat dissipation seat, a heat dissipation fan and a fan cover. The heat dissipation seat is fixedly installed at the bottom of the laser optical resonance cavity. The heat dissipation fans are provided in plurality and fixedly installed at the bottom of the heat dissipation seat. The fan cover is provided on the outside of the plurality of heat dissipation fans and fixedly installed on the heat dissipation seat.

[0009] As a preferred technical solution of the utility model, the heat sink is made of high thermal conductivity brass material, and a plurality of heat sink fins are integrally formed on the heat sink.

[0010] As a preferred technical solution of the utility model, a nylon gasket is provided between the beam combiner and the mounting column head.

[0011] As a preferred technical solution of the utility model, the end of the mounting column head is inclined at 45 degrees toward the red light head.

[0012] As a preferred technical solution of the present utility model, a second power supply interface is provided on the top of the red light adjustment seat and the second power supply interface is electrically connected to the red light head.

[0013] The beneficial effects achieved by the utility model are:

[0014] After the combination of the beam combiner and the red light adjustment seat, the red light head is located in front of the beam combiner; before passing through the beam combiner, the red light is perpendicular to the laser emitted by the laser. When the red light hits the beam combiner, the red light is reflected vertically. At this time, the red light and the emitted laser are coaxial. The red light can be adjusted through the adjustment hole on the red light seat. In summary, before using this product, when the laser needs red light to indicate the operation, the red light needs to be installed separately, and precise adjustment is required, which is very inconvenient. This product does not need to install and adjust the red light indication separately. The laser and red light are integrated and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
