As a high-tech application, laser technology has been widely used in our daily lives. It can not only be used in medical treatment, scientific research and other fields, but also bring more convenience and comfort to our lives. Laser band classification refers to classifying laser light according to wavelength range. Laser bands are usually divided into three categories: infrared, visible light and ultraviolet. The laser application range of each band is different. Their characteristics and applications will be introduced below.
I. Infrared laser band
The wavelength range of the infrared laser band is 0.78 ~ 1000 microns, which is the longest wavelength laser band. Infrared laser has strong penetrating ability and short pulse time, can penetrate air and atmosphere, and has a wide range of application scenarios.
1. Near-infrared laser
The wavelength range of the near-infrared laser band is 0.78 ~ 1.4 microns. It is a laser band widely used in fields such as medicine, communications and industry. In the medical field, near-infrared lasers can be used to treat diseases such as pain, injury and inflammation, and can also be used for detection of optical microscopes, X-ray scanners and other instruments. In the field of communications, near-infrared lasers can be used to transmit high-speed data, images and other information.
2. Mid-infrared laser
The mid-infrared laser band has a wavelength range of 1.4 to 3 microns. It is a laser band that is widely used in fields such as medicine, environmental monitoring, and industry. In the medical field, mid-infrared lasers can be used to treat diseases such as cancer, skin diseases, and eye diseases; in environmental monitoring, mid-infrared lasers can be used to detect pollutants and gaseous substances in the atmosphere, and can also be used to detect alcohol and drugs. and other substances.
3. Far-infrared laser
The wavelength range of the far-infrared laser band is 3 ~ 1000 microns. It is a laser band that is widely used in life sciences, security and environmental monitoring and other fields. In the field of security, far-infrared lasers can be used to detect the temperature and shape of objects, and can also be used to detect devices such as infrared television systems and infrared night vision devices. In the field of life sciences, far-infrared laser can be used to detect the structure of molecules such as proteins, DNA and RNA, and can also be used for biological thermal imaging and in vivo optical imaging.
Ⅱ. Visible laser band
The wavelength range of the visible light laser band is 0.39 ~ 0.78 microns, which is the wavelength band of light that can be perceived by the human eye. Visible light laser has strong penetrating ability and short pulse time, and its forms include continuous wave light, pulsed light and frequency light.
1. Ultraviolet visible light
The wavelength range of the ultraviolet visible light band is 0.39 ~ 0.45 microns. Its spectral characteristics are short wavelength, fast wave speed, large wavelength difference, and good reflection and penetration capabilities. In scientific fields such as physics, chemistry, and biology, UV-visible light can be used for applications such as fluorescence spectrum analysis, substance detection, and photochemical reactions. It can also be used in fields such as water quality monitoring and ultraviolet radiation detection.

Ⅲ. Ultraviolet laser band
The wavelength range of the ultraviolet laser band is 0.1 ~ 0.39 microns, which is the laser band with the shortest wavelength. Ultraviolet laser has strong energy and short pulse time, which can penetrate most materials and cause reaction processes such as ionization and photochemical reactions of molecules in the materials. Therefore, UV lasers have a wide range of applications in fields such as electronics, physics, chemistry, and life sciences.
1. Vacuum UV laser
The wavelength range of the vacuum ultraviolet laser band is 0.1 ~ 0.2 microns, which is the laser band with the shortest wavelength. Vacuum ultraviolet lasers can be used for the study of optoelectronics and ionization processes, as well as for applications such as microfabrication of semiconductors and manufacturing of electronic devices.
2. Near ultraviolet laser
The wavelength range of the near-ultraviolet laser band is 0.2 ~ 0.39 microns, which has high energy and short pulse time. Near-ultraviolet lasers can be used to manufacture high-precision optical components and semiconductor devices, as well as for imaging and detection in fields such as nanotechnology, biology and medicine.
The above is a detailed introduction to the classification of laser bands. It can be seen that different bands have different characteristics and application scenarios. Laser technology plays an important role in fields such as science and technology, medicine, and industry. With the continuous development of laser technology, I believe its application fields will become more extensive.
