Manhart What is the working principle of a handheld laser machine?

The working principle of a handheld laser machine can be summarized into the following steps:
1. * * Conversion of electrical energy into laser energy * *:
-The handheld laser device contains a laser inside, whose core function is to convert electrical energy into laser energy.
2. Beam output system:
-The laser beam generated by the laser will be processed through a beam output system. This typically involves using a lens system to bind the laser beam together, ensuring beam focusing and stability.
3. * * Focused laser beam * *:
-Focusing is a crucial step in laser processing. By adjusting the lens system, the laser beam is focused onto a very small point on the surface of the workpiece. This focused laser beam has a very high energy density.
4. Interaction between laser and workpiece surface:
-When the focused laser beam is irradiated on the surface of the workpiece, it will undergo physical or chemical reactions with the material on the surface of the workpiece. These effects may include melting, evaporation, oxidation, or etching, depending on the workpiece material and laser parameters.
5. * * Generate marking or processing effects * *:
-The interaction between laser and workpiece surface causes local changes in the material of the workpiece surface, resulting in permanent marking or processing effects. These effects can be text, patterns, perforations, or other forms of surface modifications.
6. * * Control System * *:
-The control system plays a crucial role throughout the entire process. It is responsible for controlling the output of the laser, focusing of the beam, and movement of the motion platform to ensure that the laser beam is processed according to the predetermined path and parameters.
Handheld laser machines are widely used in various industries, such as leather, wood, paper, plastic, electronic devices, etc. Their working principle is based on the above steps, combined with specific workpiece materials and processing requirements, to achieve different processing effects by adjusting laser parameters and control methods. Meanwhile, handheld laser machines also have the advantages of high flexibility, fast processing speed, and high precision, making them an indispensable tool in modern manufacturing.
