There is an act extension (not sure if you can get this, or if it is free to students), that has a moving heat source. Please see the link for more information:
Also there might have been some posts related to this so you might want to search the forum. E.g., see this which is very similar to your question: https://studentcommunity.ansys.com/thread/moving-heat-load-in-ansys-apdl/?order=all#comment-c5efcf1d-3d29-4b5c-9ae5-a9c2012d15fb
In any way it should be possible, I have never done this though in ANSYS, only in Strand7 where there is a moving load module (both force and heat), used for the design of bridges. Also in ABAQUS some researches/engineers have used the UMAT, DFLUX to implement this, there are some subroutines which one can have a look at and get an idea how this is done (written in Fortran). Not sure if there is a similar one in ANSYS.
So there are different options. Basically I suppose you want to run and stop (use restarts) moving your laser spot to the next location (find nearest node to apply temperatures to), and continue doing that in a transient heat analysis until you have travelled the path you need. With some apdl scripting it should be possible. Perhaps some other students have some advice or scripts that could get you started.
