RF tube Co2 laser Beauty equipment

The principle of RF laser uses RF power supply as the pump source. Two rectangular metal strips are placed in parallel, with a spacing of several millimeters between them. Different lasers have different intervals. One electrode plate is grounded through the metal shell and named as the negative plate. The other is connected to the RF power supply through the RF feed device and named as the positive plate. Two total mirrors are installed at both ends of two metal strips to form a laser resonator for extracting laser. The positive and negative plates and laser cavity mirrors are installed inside the sealed metal cavity, which is usually made of aluminum alloy.
The laser working gas, positive and negative electrode plates and laser cavity mirror are sealed in the metal cavity. The RF power is introduced into the electrode plates through a special feeder, ionizing the working gas between the electrode plates, and generating gain substances. The laser output is extracted through the cavity mirrors installed at both ends of the electrode plates. The laser beam is output from the window on the sealed cavity. The window is sealed with ZnSe mirrors coated with antireflection film, which can not only extract laser energy efficiently, but also stabilize and reliably seal the cavity with high vacuum. There is a water circuit inside the positive plate and negative plate, and both plates need to be forced cooled by water. The water circuit of the positive plate shall be specially designed to ensure that the positive plate is insulated from the outside and water can flow smoothly.
