Hi Professor Fang,

I am writing to enquire about how can I enter pulse laser parameters such as laser energy, pulse repetition time, and laser power in the software.

I look forward to hearing from you

Thank you.

hi Parvane,

please see this previous question&reply.

basically mcx/mmc solves for the impuse response function (or TPSF - temporal point spread function), where the source is assumed to be a delta function at t=0. If you have an arbitrary pulse shape, all you need to do is to convolve the pulse temporal signal with the TPSF obtained at each voxel (or at each detector using mcxdettpsf.m). This convolution can be done as a post processing.

Let me know if this makes sense.

Qianqian

Thank you.

Hello Professor Fang

Many thanks for your assistance in our project. Your answer helped me a lot.

Can you guide me? I have a question How to enter the output data of MCX program in Comsol program ?

happy to help, but you need to provide more details. what output data? what format does comsol need?

in general, mcx deals with voxelated domain, while comsol is an FEM solver which handles meshes. so, if you need mesh, you should look into mmc instead of mcx.
