Gaussian beam wavefront
Websame beam by creating a larger Gaussian beam with a negative wavefront curvature at some x < 0. This we can easily do with a lens, as shown in Figure 3. Figure 3 When normalized to the total power of the beam, P(∞) in watts, the curve is the same as that for intensity, but with the ordinate inverted. Nearly 100% of the power is contained in a ... WebFirst, the Gaussian fundamental mode is introduced as the beam solution jointly minimizing both beam divergence and beam diameter. Basic concepts such as Rayleigh length, beam waist, wave front curvature, and Gouy’s phase are introduced. Following, Hermite-Gauss beams with complex arguments in the Hermite functions (also called
