Description
This lecture covers the properties and applications of Gaussian beams, including beam quality, telescope systems, spot size, and mask projection imaging. It explains concepts such as Rayleigh range, depth of focus, beam parameter product, and intensity distribution in Gaussian beams. The instructor discusses the comparison between Gaussian beams and plane waves, the focusing of Gaussian beams, and the M² factor for beam quality evaluation. Additionally, the lecture explores optical fibers, acceptance angles, numerical apertures, and laser diode stacks. It concludes with the discussion of mask projection systems, laser micromachining systems, and materials for laser ablation masks.
