Fused silica glass boasts unique properties in the optical field: it is capable of transmitting far-ultraviolet spectra, making it the high-quality ultraviolet-transparent material. It also transmits visible and near-infrared spectra, and users can select grades for any wavelength band from 185 to 3500 mμ as required. Undoped fused silica glass appears completely transparent. When light strikes this material, it interacts with the fused silica glass through several different mechanisms, which depend on the wavelength of the light. A small portion of the light is reflected from the interaction between light waves and fused silica glass, while the vast majority is transmitted—this is why the material is also referred to as an optically transparent material.
II. Doping Properties
Cerium-Doped Fused Silica Glass
Produced from imported high-purity silica sand as the raw material with a small amount of cerium added to block ultraviolet rays, it primarily absorbs all ultraviolet radiation to maximize the light transmission efficiency within the visible spectrum range. It is used for xenon lamps as optical pumps for solid-state lasers, optical filtering in solid-state lasers, and as a light source material for other types of lasers.
Europium-Doped Fused Silica Glass
Manufactured from imported high-purity silica sand as the raw material with a small amount of europium added, it is a light source material that emits radiation at a specific wavelength. It is applied as a pump light source for solid-state lasers and in the production of various irradiation components.
Titanium-Doped Fused Silica Glass
Made from imported high-purity silica sand as the raw material with a small amount of titanium added, it resists intense ultraviolet radiation and does not generate ozone. It is used for ultraviolet-transmitting germicidal ozone lamps and other light source lamps.
Samarium-Doped Fused Silica Glass
It blocks the 1060 nm wavelength band and ultraviolet pump light emitted from components such as neodymium-doped yttrium aluminum garnet (Nd:YAG) and neodymium glass (Nd:glass). It can be fabricated into laser cavities and used for cavity applications in pump lasers.
