Description

Technical Field

[0001] The utility model relates to the field of lasers, and particularly relates to a portable Q-switching laser. Background Art

[0002] Firstly, the structure of the traditional active Q-switching laser is large in volume and high in weight. Therefore, the integrated medical laser device is not conducive to transportation and carrying, and sufficient transportation cycle and additional transportation costs are required for treatment requirements at different locations. Due to reasons such as the large volume and high quality of the laser, operators generally need to use transmission devices such as light guiding arms to achieve laser transmission in order to lead the laser to the treatment target surface. In this way of transmitting through the light guiding arm, if the quality of the optical elements is not good during the transmission process, the energy of the original laser will be greatly lost, and changes in the spot distribution and morphology will occur, affecting the treatment effect. Moreover, due to the addition of many optical elements, the maintenance cost is very high. Secondly, due to the large size of the structure of the traditional active Q-switching laser, the materials used for the required structural parts also increase accordingly. For laser manufacturers, the production cost is high and the processing cycle is long, which is not conducive to mass production. Thirdly, in terms of equipment integration, generally a large machine frame is used for installation, and a series of problems such as vibration isolation and fixation of the laser need to be considered, which increases the difficulty of equipment integration, makes the R & D cycle of equipment integration longer, and the cost increases. There are also certain strength requirements for the frame of equipment integration. Insufficient strength will generate a series of unstable factors in optics and structure, which is not conducive to the long-term reliable operation of the equipment itself. Summary of the Invention
