SNLO
SNLO (Select NonLinear Optics )
is a Windows based program developed by Dr. Arlee Smith for
selecting a nonlinear crystal and in modeling nonlinear
frequency conversion processes in those crystals. Over
fifty crystals are contained in the database. SNLO is free and may be downloaded
from www.asphotonics.com.
Instruction for use of SNLO to select crystals is
here.
Please do not hesitate to contact Newlight
Photonics Inc. in crystal
selection if you don't bother to explore SNLO. Our experienced engineers will be
more than pleased in assisting you to make a decision.
Calculating Characteristics of Noncollinear Phase Matching
in Uniaxial and Biaxial Crystals
Numerical method and FORTRAN program developed by Alan Migdall of NIST,
allows calculations of both the collinear and noncollinear phase matching, and
allows a very large set of nonlinear crystals and configurations to be studied.

Gaussian Beam: Focused Spot Size calculator
This
program calculates
the focused spot size (d) of a Gaussian beam using the formula d=4WF/(3.14D)
where W is the wavelength, D the 1/eČ
diameter and F the focus length. The peak power
density (I) of a focused laser can be estimated from the following formula,
I ~ (pulse energy)/(pulse
width)/(3.14*(0.5*d)^2).
Index of Refraction Calculator
www.luxpop.com. It returns
the refractive index at your input wavelength for most of the common substances,
e.g. KTP, KDP,BBO,LiNbO3,YAG,YVO4,Calcite,fused silica ...
www.refractiveindex.info. This is a very comprehensive refractive index data
base for crystals, glasses, metals, and gases. Sellmeier equations and the
Brewster angles for these materials can be found here.
