Example Embodiment
[0023] Specific implementation manner two: combination Figure 5 Note that the quadruple frequency target window window guide assembly 404 of this embodiment includes a vacuum window glass assembly 602, a lens roller 605, a quadruple frequency window frame 603, and two quadruple frequency target chamber vacuum window guide plates 601; A quadruple frequency window frame 603 is arranged obliquely between the vacuum window guide plates 601 of the frequency doubling target chamber. The vacuum window glass assembly 602 is installed in the quadruple frequency window frame 603, on both sides of the quadruple frequency window frame 603. A lens roller 605 is installed. The opposite sides of the two quadruple frequency target chamber vacuum window guide plates 601 are provided with roller grooves 6011. The lens roller 605 is arranged in the roller groove 6011 and can roll up and down in the lens roller groove 6011. The frequency doubling window frame 603 is encapsulated on the flange 506 ...
Example Embodiment
[0024] Specific implementation mode three: combination Figure 6-Figure 9 It is explained that the quadruple frequency angle adjustment mechanism 504 of this embodiment further includes a first frame 704, a second frame 706, a third frame 707, a quadruple frequency inner frame 708, and a quadruple frequency crystal assembly 11-7. A frame 704, a second frame 706, and a third frame 707 are sequentially connected along the light emitting direction. The second frame 706 is provided with a yaw rotation connection pair connected to the first frame 704 in the horizontal direction. The micro-drive mechanism 701 passes through the first frame 704 and is connected to the upper or lower part of the second frame 706. The yaw micro-drive mechanism 701 realizes the vertical swing of the second frame 706 through the yaw rotation connection pair, and the inner frame 708 Installed in the second frame 706, the inner frame 708 and the second frame 706 are provided with a pitch rotation connection ...
