ConjugaWave is a specialized optical calculator that simplifies the evaluation of phase conjugation efficiency in nonlinear media. By combining user inputs for nonlinear coefficient, pump intensity, and interaction length, it provides an instant estimate of how effectively a conjugate wave can be generated. Designed with a clean gradient interface and intuitive controls, the app makes complex optical physics accessible for quick checks, educational purposes, and preliminary research insights in wavefront correction and adaptive optics.
