NLO Conversion Calculation

--A must for both experts and beginners seeking
non-linear optical conversion solutions!

CASIX is pleased to announce the first Windows based software dedicated for Non-linear Optical Conversion calculation in the non-linear optical material industry. The software NLO provides strong capability for the following:

1. Calculation of phase matching angle along with acceptance angle, spetral and temperature bandwidth for all kinds of non-linear optical crystals -- both well documented crystal and exotic crystals, as well as cutomer defined ones. Calculation is applied to both critical phase matching (CPM) and non-critical phase-matching (NCPM), as well as unconventional phase matching schemes made by the customer.

2. Calculation of efficiencies for SHG,SFG,DFM and OPA processes. Allow the customer to easily change the input beam parameters so as to maximize efficiency.

3. A dozen of linear optical co-efficients are also available along with the non-linear optical constants. These include refractive index, GVM, walk-off angle, etc. It also allows the user to calculate ultra-short pulse broadening.

4. References/Applications are hyper-text linked to the program -- allow the user to get detailed information about the special applications of the crystal.

Note: This program is NOT a shareware,you can download it now and ask for a access number by e-mail. If you feel satisfied and want to use it, You Should Pay For It, otherwise everything should be uninstalled.

Waveplate Designer

--Chooseing any wavelength from 300nm to 2000nm

In order to help customers have a clear picture of Quartz crystal wave plate bandwidth, CASIX develop an interface program? WAVEPLATE. With this program, you can choose any wavelength(from 300nm to 2000nm) and any order as you want, the type of waveplate(?/2,?/4,?/8,?)also can be selected from dialogue frame. After these have been prepared, click the 'compute' button, results will be listed out. The results are from zero order to the order that you have chosen. At each order, results conclude thickness(optical thickness but not true thickness), spectral-bandwidth(D?),temperature-bandwidth(DT),angular-bandwidth(D?),and retardation tolerance change rate by wavelength(dK/d?) ,by temperature(dK/dT) ,by incident angle(dK/d?).These results are all under the condition that extinction ratio is 1/100.Moreover, the birefringent(Dn) of this wavelength is put out.

E.g. if you choose wavelength 532nm, order 0, the type of waveplate 1/4, then the results will be as following.

From the table above, we can change the wavelength from 532-30.6nm to 532+30.6nm under the condition that extinction ratio is 1/100, and retardation tolerance will change dK/d? by changing 1nm around center wavelength 532nm. Temperature and incident angle are versa. Our center temperature and incident angle respectively is room temperature and 0.

You may calculate the parameters with our program by downloading it freely. It's easy to use.
