Calculator Instructions / Annotations:


With the APE Calculator, often needed (non)linear equations can be easily evaluated. This includes Sum Frequency Generation (SFG), Difference Frequency Generation (DFG), the wavelength relations in an optical parametric oscillator (OPO) as well as in coherent anti-Stokes Raman scattering (CARS) spectroscopy.

The conversion between wavelength, wavenumber, and frequency as well as different characterizations of pulses can be calculated.

The APE Calculator is now also available as free Android APP. Internet download here.
