Laser modules and laser systems
With the rapid development of artificial intelligence and the Internet of Things (AIOT), the application of laser modules has ushered in a broader development space. Traditional laser modules are mostly visible light, mainly used in the field of indication and sensors, such as laser pointers and handheld laser rangefinders, which are mainly convenient for human eyes to see. Infrared laser module, as a substitute for visible light, has the characteristics of monochromaticity and narrow bandwidth, which can simplify image processing, match specific receiving spectrum, and improve the overall efficiency of the system.
In robot navigation and obstacle avoidance, 808nm, 850nm and 940nm are commonly used wavelengths, which are invisible to the human eye. They have been widely used in sweepers, 3D scanning, machine vision, etc. Traditional laser modules are mostly edge-emitting lasers. Due to the higher cost, lower reliability, and larger size of edge-emitting lasers, they cannot well meet the growing market demand for AIOT. VCSEL vertical cavity surface emitting lasers have the advantages of low cost, high reliability, surface packaging, etc., and become the best choice for replacing edge emitting lasers in AIOT applications. Laser systems are customized complete solutions for most different applications such as laser welding systems, laser cutting systems, laser marking systems and various other laser system solutions. Laser technology, mechanical engineering, software and process development are the decisive key disciplines for product quality, functionality and cost-efficiency. Complete solutions from Coherent-ROFIN are solutions from a single source.
