The APE Optics Calculator app is designed to help users evaluate nonlinear equations, including sum frequency generation, difference frequency generation, the wavelength relations in an optical parametric oscillator, and in coherent anti-Stokes Raman scattering (CARS) spectroscopy.
IS THERE AN APP FOR THAT?
APP NAME: APE Optics Calculator
OFFERED BY: Stefan Popien
PLATFORMS: Android (requires 1.6 and up); iPhone, iPad, and iPod (requires iOS 6.1 or later; optimized for iPhone 5)
WHAT IT DOES: The APE Optics Calculator app is designed to help users evaluate nonlinear equations, including sum frequency generation, difference frequency generation, the wavelength relations in an optical parametric oscillator, and in coherent anti-Stokes Raman scattering (CARS) spectroscopy. Reportedly, the conversion between wavelength, wavenumber, and frequency as well as different characterizations of pulses can be calculated.
