Beam quality is a critical factor that impacts the cutting process in laser cutting machines. A perfect laser beam with high beam quality produces a tightly focused beam with a small spot size, high power density, and low divergence. This allows the laser to cut with precision, speed, and accuracy, resulting in clean and smooth cuts with minimal heat-affected zones (HAZ) and minimal material waste.
In contrast, low beam quality results in a larger spot size, low power density, and high divergence. This leads to slower cutting speeds, inaccurate cuts, and rough edges with a significant HAZ. In addition, low beam quality also requires higher laser power, resulting in increased operating costs and reduced machine lifespan.
Therefore, having high beam quality is essential for achieving optimal cutting performance, reducing operating costs, and improving overall machine efficiency.
