SNLO (Select Non-Linear Optics) is a Windows based program developed by Dr. Arlee Smith (formerly with Sandia National Labs) for selecting a nonlinear crystal and 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.as-photonics.com. Instruction for use of SNLO to select crystals is here.
Please do not hesitate to contact Newlight Photonics 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.

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/e² 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).
