The principle of laser marking is to mark the surface of a wide variety of materials with a laser beam. The laser uses high energy to change the material composition or chemical information on the surface of the substances and to engrave traces that can have the required etching patterns and characters. Laser marking is a time-saving, flexible and programmable, non-contact technology that can be used specifically for the production of systems with complex architecture and requiring a long service life. In addition, laser marking technology is widely used in large-scale industrial production lines for hardware, packaging, 3C electronics and others. It is ideal for processing various materials such as metal, plastic, wood, paint and glass.

Satellite communication has grown dramatically in recent years due to advancements in contemporary communication technology. The capabilities of navigation and communication satellites were progressively enhanced and, in certain cases effectively brought to market. Low-orbit satellite communication can offer adaptable and affordable communications options for remote areas. It ensures smooth worldwide coverage to prevent communication blind spots by offering information support services for a range of scenarios, including flights, scientific research, maritime operations, and disaster management.

Laser beam remote sensing technology uses a laser beam to capture the target to be measured over long distances that depend heavily on the light source and detector. The key benefits of this technology include high precision, large information capacity, and compact equipment. Vehicle-mounted fiber optic LiDAR is a sophisticated sensor for environmental perception that integrates light source and detector and is essential to intelligent driving. It offers highly accurate environmental perception with multiple information such as distance, angle, intensity, and speed, and has a high resistance to interference.

Laser therapy uses a tight, concentrated light beam of specific wavelengths to perform surgical procedures in areas that need a lot of detail or concentration. This is based on mechanisms such as the photothermal effect, the photochemical effect, and the biological stimulation effect. By absorbing and converting light energy into thermal energy through organ tissue substances, laser therapy is used in many areas of medicine, including the treating cancer, sealing blood vessels, eye surgery, skin treatments, destruction of lesion cells, and pulverizing foreign bodies. Laser therapy offers many benefits, including reduced bleeding, painless, minimally invasive treatment, a high level of safety, quick recovery after surgery, and few side effects, which is becoming increasingly important in the medical field. The application includes laser lithotripsy of the urinary system, laser prostatectomy, minimally invasive surgery of the throat and closure of varicose veins.
