A·P·E Calculator

Our helpful online tool conveniently evaluates often needed equations and is also available for many smartphones and tablets.

Calculator Instructions / Annotations

The A·P·E Calculator helps to easily evaluate often needed (non)linear equations. 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 A·P·E Calculator is available for devices with AndroidTM OS 1.6 and upwards as well as Blackberry Tablet OS 2.0 and upwards.
