Webparameters of the input beams do not match the cavity eigenmodes.2 If an input beam is slightly misaligned in angle or transversely displaced with respect to the cavity axis, first-order Hermite–Gauss modes are introduced. Sampas and Anderson3 and Hefetz et al.4 have demonstrated that, by using phase modulation WebDepending on the cavity design, there are tens of degrees of freedom of the optical elements, which can never be perfectly aligned. Here, we study …
