Second Harmonic Efficiency Calculator

As its name makes it quite apparent, Second Harmonic Efficiency Calculator is a straightforward and highly-specialized piece of software designed to help users calculate the output power for a second-harmonic generation (or SHG), and its reverse process, the spontaneous parametric down-conversion (SPDC for short).

The first process, the SHG, joins two input photons into one output photon. The energy of this output photon is the result of the energy of the two input photons combined. The reverse process mentioned above, the SPDC, splits an input photo into two output photons with correlated polarization and lower energy.

As long as users ensure that NET. Framework 4.6.2 is running on their computers, they should have no problems deploying Second Harmonic Efficiency Calculator on any machine thanks to a run-of-the-mill installation procedure.

As one might expect from a high-specialized application such as this, the way it looks is not that relevant. The application has a singular window without menus or other typical GUI elements one might expect.

The upside is that users have a very easy time inputting all the required information and data in order to obtain results instantly. Because the two processes happen at very high light intensities, a laser beam is needed as input light.

To get started, users only need to enter the frequency of the incident laser, the laser power, the incident pulse duration, and the nonlinear crystal length. Then, they need to follow up by adding data for the area on which the last is incident on the crystal, the refractive index of the crystal, the refractive index of the crystal for SHF, the refractive index of the crystal for down-converted frequency, the nonlinear coefficient of the crystal, and to select the nonlinear crystal coefficients from the list.

Upon hitting the “Calculate power of frequency-converted light” button, users are instantly provided with the results (the output parametric down-conversion power and the output second-harmonic power) in the bottom half of the app’s main window.

To end with, Second Harmonic Efficiency Calculator may not be the most stylish app out there, but it does its job right, in a very efficient manner, one accessible to all categories of users.
