Power output: The power output of the laser source determines the cutting speed and thickness capacity of the materials that the machine can effectively process. Higher power outputs allow for faster cutting speeds and the ability to handle thicker materials.

Beam quality: A high-quality laser beam ensures precise cutting results, smooth edges, and minimal material waste. Beam quality is influenced by factors such as the laser's mode structure and brightness.

Reliability and stability: The laser source should be reliable and stable, with consistent performance over extended periods of operation. This characteristic is crucial for maintaining the machine's productivity and reducing downtime.
