FIGURE 1. As laser energy increases, the necessity of higher quality and precision optics and coatings causes the cost of the beam expander to increase (a). Increasing the input aperture size increases the cost of the beam expander rapidly at larger input apertures because of the nonlinear dependence of aberrations on input beam diameter (b). With a fixed design, increasing the input aperture leads to a decrease in performance as aberrations start to dominate the wavefront (c).
