Your tutorials are a gem, Sir, especially to someone like me who recently started learning on Comsol ! I really appreciate the fact that you took the time to put this content out there, especially that not many RUclips channels are covering Comsol topics, which is weird to me ! There are countless of interesting optical (nanophotnics) topics that can be covered. I have a small inquiry, if you don't mind of course. I have been trying to simulate the photo-induced force microscopy on Comsol, which is basically an AFM system that is equipped with a QCL Mid-IR laser illuminating the tip-sample junction at 45 degrees. One of the things that I am mightily struggling with is knowing which EM wave function to use to simulate this QCL IR-laser behavior across a range of frequencies. Is it possible to point me in the right direction with this?
Thank you. Kindly refer to the link below. I've added some documentation and files for practive purposes. drive.google.com/drive/folders/1I-mGqcsMVBXRzfswoPwOL1ZcTH2dipCd?usp=share_link
@@kabindaex7047 My apologies for the late answer I am very appreciative of your tremendous help and for taking the time to answer me. I will look into into the files that you have shared with me, they do seem interesting and relevant for my topic. Thank you again
Gaussian beam profile sometimes is done using a normalization of the Gaussian in the following equation: (p_laser/(2*pi*r_spot^2))*exp(-r_focus^2/(2*r_spot^2)) However, most gaussian beam profile are given in the following instead: ((2*p_laser)/(pi*r_spot^2))*exp(-(2*r_focus^2)/r_spot^2) Note that p_laser is the variable. Here are some links for further research: en.wikipedia.org/wiki/Gaussian_beam www.edmundoptics.com/knowledge-center/application-notes/lasers/gaussian-beam-propagation/ www.sciencedirect.com/topics/engineering/gaussian-profile-beam
nice work thank u, can u give similar example AC magnetic field instead of laser and magnetic nanoparticles instead of silicon wafer. a kind of induction heating but this is based on brownian and neel relations.
Thanks. Made my first Comsol simulation with your help!

@@youssefelhelou4814 You are welcome.
Nice sir Can you please demonstrate for laser texture and its effect in optical characteristics
Good work Sir, l was eager, if you include the laser ablation with Level set Method or Deform geometry interface.
Can u explain about laser machining in comsol multiphysics
Hi..... Happy New Year Sir... Can you please make a video for simulation on Laser additive manufacturing/ Laser CLADDING using COMSOL MULTIPHYSICS
Thank you, happy new year to you as well. I'll try to do such.
Cool bro.
Hi bro, I have one question.
Can you explain, how u got 2 before the p_laser. Why it was multiplied by 2?

Thank you. I would surely try.
