Rayleigh beam
WebApr 11, 2024 · For calculating the focused laser beam, we use the Rayleigh Formula (1) to calculate the Rayleigh length, which is determined by the beam waist radius and wavelength . (1) At present, the most commonly used laser wave lengths in the market are 1064 nm, 532 nm, and 355 nm. In our method, we focus on = 1 mm and = 532 nm. WebThe total kinetic energy in the beam is then obtained by integration . This is a maximum when . which occurs simultaneously at all points on the beam. Therefore the maximum …
