The indico page for the meeting is there and the OSCAR presentation here.
I have defined my cavity but when I do a scan over one FSR, I can see the presence of some second order modes. Or when I look at the reflected power, I can see a mode LG10 or I do not have the maximum power gain. All that may indicate that the mode matching […]
First the beam size must be large enough to never clip the laser beam, at any distance in the simulation. For example the grid size must be 5 times the largest beam radius. The second point, if the clipping losses are important is to have the grid size larger than the largest aperture in the […]
