[0030] Step 100, placing the diamond crystal in a vacuum chamber, and making the diamond surface reach a preset temperature, and the preset temperature is 200°C-1000°C.

[0031] In step 200, a silicon layer is spread on the surface of the diamond crystal to form a film structure, and in the film structure, a silicon carbide layer is formed at the interface between the silicon layer and the diamond crystal.

[0032] Step 300, coating a target film layer on the surface of the film structure to form a diamond crystal-based film structure.

[0033] In this step 300 , specifically, the step of pla...

Embodiment 1

[0046] In the present embodiment, the preparation method of the high bonding force optical film of diamond crystal comprises the following steps:

[0047] Place the diamond crystal 21 in the vacuum chamber 11 of the coating device and fix it on the stage 12. The working temperature is controlled by the pre-laying temperature controller 12 to 200°C, and the pre-laying silicon layer value of the thickness controller 15 is set. The thickness is 0.1nm, and the required silicon material is provided by the film tray 13, and a silicon layer is laid on the surface of the diamond crystal 21 by ion beam sputtering technology to form a film structure. During this process, the thickness controller 15 detects the thickness of the tiled silicon layer and feeds it back to the thickness controller 15. When the thickness of the tiled silicon layer reaches 0.1 nm, the laying of the silicon layer is stopped. During this process, the silicon carbide layer 23 is formed at the contact interface bet...

Description

[0001] The invention relates to the technical field of coating, in particular to a diamond crystal high-binding force optical film and a preparation method thereof. Background technique [0002] Raman laser technology has the characteristics of beam quality optimization effect, pulse compression effect, narrow linewidth output, etc., and is an important technology to realize laser wavelength expansion. Diamond crystal has the advantages of wide light transmission range, high thermal conductivity, and large Raman frequency shift coefficient, and it is an important research direction of Raman laser technology in recent years. [0003] The diamond crystal structure is stable and has no dangling bonds, which makes the existing coating technology difficult. The film system is unstable, has low damage resistance, and is easy to fall off. This is one of the important technical problems to be solved by diamond Raman laser technology.
