I have continued to develop a computer program for calculating non-collinear phasematching parameters and other useful quantities related to downconversion. I developed this program while working at NIST, and still periodically receive incquiries, so I've published the program as it stands (as of 2008). To install the program
- Download the following zip file: Phasematch.zip
- Extract the contents to a known place (e.g. a folder on the desktop)
- Run "setup.exe"
The computational portion of the code is written in Fortran. The graphical front end is a small Labview application that calls the Fortran library and displays the plots. The Fortran source code is also included in the zip file. I continue to develop this code, so if you find bugs let me know.
