CVD single crystal diamond properties:
Since CVD diamond does not contain any metal catalysts, its thermal stability is close to that of natural diamond. Like high temperature and high pressure artificially synthesized polycrystalline diamond, CVD diamond grains are also arranged in disorder, without brittle cleavage planes, so they are isotropic.
Diamond has an exceptionally high transmission over a very broad range of wavelengths and low scatter in IR applications. It is extremely hard and chemically inert; making CVD diamond the optimal choice in applications demanding higher power, larger area, and resistance to hazardous materials or greater strength. These abilities also enable smaller material geometries to be used, which opens up new lightweight applications. Advances in the creation and shaping of diamond enable us to provide solutions to novel optical problems.
Application
| High power CO₂ lasers | |
| Long wavelength IR imaging (8-14 micron) | |
| Spectroscopy | |
| High power RF generators and gyrotrons | |
| Disc lasers | |
| Raman lasers | |
| VECSELs | |
| Diamond lenses |
Key product features:
| • Extremely broad transmission spectrum 1. The refractive index of diamond should be ~2.4. We need to achieve broad and high transmission in the mid-infrared at wavelengths from 1 micron to 30 microns. 2. The surface roughness should be well below 50nm for good transmission from 1μm wavelength, 3. The error should not exceed 0.2mm, 4. Applied to infrared radiation measuring device, the triangular diamond prism is good for mid-infrared transmission. |
