(CW) continuous laser and (QCW) quasi-continuous laser！

CW, the full name is "Continuous Wave", translated as continuous wave laser, specifically refers to those devices that can provide uninterrupted laser output during operation. The characteristic of this laser is that it can continue to emit laser light until the end of the operation. CW lasers are known for their lower peak power and higher average power compared to other laser types. Due to its continuous output characteristics, it is widely used in metal cutting, copper and aluminum welding and other fields, becoming one of the most common and widely used types of laser. Its ability to provide continuous and stable energy output makes it particularly important in both precision machining and mass production. When debugging the continuous laser process, we mainly focus on several key parameters, including power waveform, defocus amount, spot core diameter and processing speed. Precise adjustment of these parameters is crucial to achieve optimal processing results and ensure high efficiency and high quality of the laser processing process.

Continuous laser energy distribution characteristics

A distinctive feature of continuous (CW) lasers is the Gaussian pattern of their energy distribution, that is, the energy distribution of the laser beam cross-section shows a Gaussian (normal distribution) shape that is highest in the center and gradually decreases outward. This distribution characteristic enables CW lasers to achieve extremely high focusing accuracy and processing effects when performing precision machining, especially in application scenarios that require highly concentrated energy.
