WebThe history of laser beam shaping is treated by Shealy in Chapter 9 of Laser Beam Shaping Applications. A flat-top laser irradiance profile can be obtained by expanding the beam to obtain a pattern with the desired degree of uniformity. This approach intrudes very large losses in energy throughput. Web4 aug. 2024 · Bear with us, the answer is technical. Lasers release energy by emitting laser beams of specific wavelengths. When the beam hits the surface, the material reflects most of its energy. The remaining energy is absorbed and converted into heat. For laser etching, the material must absorb just enough energy to melt.
