Application fields of ultraviolet laser

UV laser is a special type of laser with a short wavelength, concentrated energy, and short pulse frequency. The wavelength range of this laser is between 200~400nm, and its high-energy photons can break chemical bonds on materials at the molecular level, thereby achieving the effect of separating and breaking materials. These characteristics make UV laser more suitable for precision processing and special material processing. Currently, UV laser has a wide range of applications in industrial production, medical treatment, scientific research and other fields.

The main application areas of ultraviolet laser include:
Material processing: UV laser can cut, carve, weld and other materials. The special properties of UV purple light make it possible to process many materials that are difficult to process with other lasers, such as glass, ceramics, jade, crystal, etc. UV laser can carve complex patterns on the surface of these materials and cut them into different shapes of parts.

Surface treatment: UV laser is good at processing the surface of materials, and the most common methods include marking and cleaning. By irradiating with UV laser, the surface material can be peeled off to form permanent marks, which are difficult to wear and have clear handwriting. UV laser marking is widely popular in many fields such as food packaging, home appliance appearance, pipeline marking, etc.
Semiconductor production: UV laser can be used for the production of chips, integrated circuits and other semiconductors. Its main usage methods include high-precision cutting, drilling, etching and other processes. The high precision and high energy characteristics of UV laser itself can improve the stability and reliability of the product manufacturing process.

Disease treatment: UV laser has been applied in various medical methods such as skin disease treatment, ophthalmic surgery, cardiovascular treatment, etc. For example, in ophthalmic surgery, UV laser can accurately cut corneal tissue, change the curvature of the cornea, and correct vision. It has the advantages of high precision, minimal trauma, and fast recovery.

Spectral analysis: Ultraviolet laser also plays an important role in scientific research. During spectral analysis, ultraviolet laser can excite fluorescent substances in the sample to produce fluorescence spectra. By analyzing the fluorescence spectra, information such as the chemical composition, molecular structure, and concentration of the sample can be obtained. This method is commonly used in fields such as chemical analysis, biomedical testing, and environmental monitoring.

In summary, ultraviolet laser is a widely used type of laser that plays a crucial role in industrial production and medical research due to its unique optical properties. Compared to other lasers, the uniqueness of ultraviolet laser gives it a more important position.
