With the arrival of digital electronics, laser technology has become an increasingly important industrial tool to meet the new functional requirements required by Industry 4.0.
The processes with laser light, that is with focused light rays, are many:
- Deposition of the material
- Production of metallurgical changes
- Sanding and cleaning of surfaces.
Basically with the laser, almost any processing can be performed.
Industry 4.0 focused on automation and data exchange. From this it follows that even the processes based on the laser must transform and become more “intelligent” to
- more power
- more efficiency.
This means having systems which can detect all process data, such as temperature, environment, power. These parameters must then be continuously adapted and monitored.
WHAT IS LASER TECHNOLOGY?
A laser is a device that emits a coherent light beam through an optical amplification process. There are many types of laser, including gas, fiber, solid state, diode and excimer lasers. All these types of lasers share a set of basic components.
The laser emits light through a process based on the stimulated emission of photons. Unlike natural sunlight, which is of many different wavelengths, emitted laser light has a single unreachable wavelength using other technologies. The beams can be focused with a lens in very small points, reaching a very high irradiance (energy per area).
Industrial laser systems are very complex for both data acquisition and processing. It follows that the data flow can not be controlled with manual methods but an “intelligent” analysis must be performed, optimized in the development laboratory and then applied to the production routine.
