With the continuous progress of science and technology, laser modules are more and more widely used in various industries, such as medical, printing, packaging, electronics industries, etc. The laser module is composed of a laser tube and a laser head module, which is a component based on laser technology. It can generate and output laser light, which has the advantages of high precision, high brightness, high stability and low power consumption.
In the electronics industry, laser modules are widely used in optical communications, optical storage, optical sensing, laser printing, and lidar.
- Optical communication field: Laser modules can be used to achieve high-speed and long-distance data transmission. Using the transmission characteristics of single-mode optical fiber, the laser module can achieve a transmission distance of tens or even hundreds of kilometers. At the same time, the modulation speed of the laser module is also very fast, and high-speed data transmission at the Gbps level can be realized. The collimation directionality of the laser beam and the high-speed propagation speed can provide high-speed and stable optical signal transmission.
- Optical storage field: The laser module can be used to read and write data. For example, storage media such as Blu-ray discs and DVDs utilize laser beam focusing and scanning technology to achieve high-density and high-speed data storage.
3.Optical sensing field: Laser modules can be used to detect information such as the position, velocity, and shape of objects. Using the interference and diffraction technology of lasers, high-precision optical sensing can be realized. Examples include areas such as robotic vision and production line inspection.
- Laser processing field: Laser module can be used for laser printing, laser engraving, laser marking, laser cutting applications. The high energy, high focus, and high collimation directivity of the laser beam enable it to micro-process the surface of materials at the nanometer level.
- Lidar field: LiDAR can be used to achieve high-precision and high-resolution measurements. Using the reflection and scattering of the laser, objects can be measured and identified with high accuracy. For example, lidar is widely used in fields such as unmanned vehicles and drones.
