Embodiment Construction
[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and a specific embodiment.
[0036] like figure 1 and 2 As shown, the present invention is a laser frequency doubling crystal frequency conversion efficiency measurement system, which mainly includes a high rigidity substrate 1, a loading plate 2, a crystal fixing frame 3, a KDP crystal element 4, an X-direction precision electric translation stage 5, and a Y-direction Precision electric translation stage 6, laser 7, U-shaped adapter frame 8, laser receiver 9, controller module 10, etc.
[0037] in:
[0038] The high-rigidity substrate 1 is a rectangular high-flatness steel plate with a size of 1800mm*1200mm*10mm, which is used to install and support the loading plate 2 and the X-direction precision electric translation table 5;
[0039] The loading plate 2 is a loading platform constructed of stainless steel, and the four legs are respectively fixed on the h...
