doughnut mode(LG01) laser in a planar undulator

Post by Jingyi » 16 May 2018, 21:16

Hi,
I want to simulate a doughnut mode (LG01 mode) laser modulation in a planar undulator. But LSRMDLTR only includes TEM01 and TEM10 mode. A linearly polarized doughnut mode is superposition of HG01 and HG10 mode with 90 degree phase delay LP= HG10+i HG01. Here HG is Hermite-Gaussian mode. Any suggestion for this? Is it possible to add an element to deal with LG01 laser mode in planar undulator?

Thanks!
Jingyi
