Products Selected Applications Company Service & Contact | Calculator | English HOME CALCULATOR Calculator The App “APE Calculator” is for solving equations from non-linear optics. With over 10,000 downloads, it is one of the most frequently used apps for this purpose. The App is intended for customers and users, who are mainly concerned with non-linear processes of ultra-short pulse laser technology (UKP). It performs the relatively simple conversion of wavelengths into wave numbers or frequencies, but can also solve more complex tasks, for example, the dispersion caused by dispersion of short pulses. Users of OPOs or users of CARS also benefit from the rapid determination of pump, signal or idler wavelengths. The Calculator is available as a web application on the desktop (www.ape-berlin.de) or as an Apple, Android and BlackBerry app. Show Calculator Instructions Wavelength Conversion Calculator SFM equation λ1 pm nm µm λ2 pm nm µm λSFM pm nm µm DFG equation λ1 pm nm µm λ2 pm nm µm λDFG pm nm µm cm-1 OPO equation λidler pm nm µm λsignal pm nm µm λpump pm nm µm CARS equation λpump pm nm µm λstokes pm nm µm λCARS pm nm µm ṽvib cm-1 2 post decimal positions maximum precision equation Wavelength - Wavenumber - Frequency Conversion vacuum wavelength λ pm nm µm wavenumber ṽ cm-1 frequency v THz GHz MHz 2 post decimal positions maximum precision equation Bandwidth Conversion wavelength Δλ pm nm µm Δλ pm nm µm wavenumber Δṽ cm-1 Δṽ cm-1 frequency Δv THz GHz MHz Δv THz GHz MHz 2 post decimal positions maximum precision equation Conversion of Bandwidth and Pulse Duration for Transform Limited Pulses Show explanatory content pulse duration Δτ fs ps ns bandwidth Δλ Δv Δṽ Δv THz GHz MHz Δṽ cm-1 Δλ nm pm µm Δλ nm pm µm time bandwidth product (TBWP) Gauss sech² Minimum TBWP for pulses with Gauss-shape: 0.44 Sech²-shape: 0.315 2 post decimal positions maximum precision equation Dispersion Calculator Show explanatory content tin duration of transform limited Gaussian pulse t'in fs ps ns t'in f2 second order group velocity dispersionof dispersive material fs² ps² tout pulse duration after travelling through dispersive material fs ps ns 2 post decimal positions maximum precision equation Propagation of Light t - propagation time fs ps ns x - propagation distance nm µm mm cm m 2 post decimal positions maximum precision News ARPES news using Angle-Resolved Photo-Emission Spectroscopy (ARPES) with our light source (80 MHz, 6.5 eV energy, < 1 meV bandwidth), Gerd... read more APE turns 29 years today.
