In the past 100 years of scientific and technological development and the leap of human civilization, the laser industry has developed rapidly. Especially in recent years, lasers have been gradually applied to various fields that are closely related to our daily lives. Here are some common uses of lasers:
- Purpose of communication:
It is the use of laser to transmit data, the basic principle is to modulate the signal to the frequency, amplitude or phase of the laser, and then transmit, because of its strong anti-interference, so it has high transmission bandwidth, large capacity and long distance;
- Medical Uses:
In terms of diagnosis, various laser analysis and diagnostic instruments (such as laser tumor diagnostic analyzer, laser holographic microscope, laser CT, etc.) can quickly and objectively obtain results. In terms of treatment, laser therapy technology (such as laser knife, laser treatment machine, laser microbeam technology, endoscopic laser, photodynamic therapy, etc.) has been applied in almost all clinical departments.
- Cosmetic uses:
The applications of lasers in the medical and aesthetic fields are mainly ophthalmology (including refractive surgery and photocoagulation), surgical, dental, therapeutic, dermatological, hair removal, and other cosmetic applications.
- Military use: Lasers are mainly used in basic research and development in scientific research and military markets, such as universities and national laboratories, as well as lasers for emerging and existing military applications, such as rangefinders, illuminators, infrared countermeasures and directed energy weapon research.
- Security use:
Lidar can be used to monitor fence boundaries for intrusions. Features such as long detection range, centimeter-level accuracy, real-time distance measurement, and adaptation to various light intensity conditions support the generation of 3D images by LiDAR.
- Industrial processing use:
Laser processing has the advantages of high precision, small distortion, no contact, energy saving, etc., and its application fields can cover almost the entire machinery manufacturing industry, including mining machinery, petrochemical industry, electric power, railway, automobile, shipbuilding, metallurgy, medical equipment, aviation, machine tools, power generation, printing, packaging, molds, pharmaceuticals and other industries. Including cutting, welding, surface treatment, punching, marking, scribing, fine-tuning and other processing processes.
- Ranging use:
Laser ranging is based on the laser as the light source for ranging. Compared with the photoelectric rangefinder, it can not only work day and night, but also improve the accuracy of ranging, significantly reduce weight and power consumption, and make the distance to distant targets such as artificial earth satellites and the moon become a reality.
- Scientific research use:
With the continuous development of ultrafast laser technology and product applications, especially the modular and large-scale production of ultrafast fiber lasers, their cost performance is getting higher and higher. At present, it has entered the ordinary laboratory and ordinary industrial processing scenarios, and will surely become a universal advanced productivity tool for scientific research and industrial processing applications.
- Information field use;
Diode lasers and fiber amplifiers are two key technologies for fiber optic communication. In addition, laser printers, laser fax machines, laser phototypesetting, laser large-screen color televisions, optical fiber cable televisions and atmospheric laser communications have been widely used.
- Recreational use:
Lasers in this field are mainly used in light shows, games, haunted houses, secret rooms, laser ponds, and digital cinemas, among others.
