In laser science, the parameter M , also known as the beam propagation ratio or beam quality factor is a measure of laser beam quality. It represents the degree of variation of a beam from an ideal Gaussian beam. It is calculated from the ratio of the beam parameter product (BPP) of the beam to that of a Gaussian beam … See more There are several ways to define the width of a beam. When measuring the beam parameter product and M , one uses the D4σ or "second moment" width of the beam to determine both the radius of the beam's waist and … See more Real laser beams are often non-Gaussian, being multi-mode or mixed-mode. Multi-mode beam propagation is often modeled by considering a so … See more M is useful because it reflects how well a collimated laser beam can be focused to a small spot, or how well a divergent laser source can be collimated. It is a better guide to beam quality than Gaussian appearance because there are many cases in which a beam can … See more • Laser beam profiler • Strehl ratio See more WebA New Perspective Samyang Optics 삼양옵틱스 렌즈에 대한 자세한 정보와 지원은 물론, 삼양옵틱스 렌즈의 매거진 콘텐츠 및 렌즈로 촬영한 멋진 작품도 만나볼 수 있습니다.
