Reverse optimization is a means of determining the internal details of a system and can identify the internal root causes of the effects to provide the exact prescription ready for immediate implementation in system improvement. We can apply the reverse optimization method to complex physical optics systems including full diffraction at all steps, laser gain, nonlinear optics, resonant oscillations, etc. using damped least squares (DLS) optimization. The targets for DLS optimization may consist of specific performance measures and wavefront or irradiance maps that may consist of many millions of points readily obtained from beam diagnostic instruments. Reformulation of the DLS mathematics allows efficient calculation and some examples illustrate the method. The classical Jacobian matrix is no longer constructed directly saving computer memory and time. Instead a system matrix of small rank is built on the fly with data points accessed the minimum number of times.
