Lasers are widely used in isotope separation, laser spectroscopy, high-resolution holography, laser weapons, material structure research, optical communications, remote sensing, integrated optics, nonlinear optics, and pumped tunable dye lasers. Laser beam expansion refers to the process of expanding the output beam of the laser using a laser beam expansion system. The principle of the laser beam expansion system is the same as that of a telescope, except that the positions of the objective lens and the imaging lens are reversed. The Keplerian beam expansion system will form an energy focusing area between the two lenses, heating the surrounding air, which may cause wavefront errors. High-power lasers may even cause air ionization, so most beam expansion systems will use a Galilean beam expansion system.
[0003] Currently, when lasers on the market need red light guidance or beam expansion operations, they can only be installed separately. The position and angle need to be adjusted to achieve the best effect, and various factors such as installation space must also be considered. The operation process is relatively complicated, affecting the operational efficiency of the laser beam expansion operation.
[0004] Therefore, in order to solve the above problems, a radio frequency CO2 laser with a coaxial red light cylindrical collimation and beam expansion device is proposed. Utility Model Content
