You probably don't need to do it. You pretty much have all the math that you need. Any additional math that you will need, you will be taught in the course that you need it for. Also most grad programs require you to take 2 grad level math courses, so you will get more math that way. If I...

maybe the IR light heated up the air around the thermometer and then the heat transferred from the air to the glass to the mercury. This could be in addition to many of the other ideas others have mentioned.

In the definition that I am using the beam waist (w0) is the radius of the fiber core not the diameter, so 28 μm is an acceptable wz for z=1mm. Any thoughts on how I can model the intensity profile as the light exits the fiber, and after passing though a lens system, or a better way to find...

I am trying to model light that (1) exits a multimode fiber (2) passes through a cylindrical lens system and (3) enters a multimode fiber (and yes I know that a cylindrical lens system is not ideal for fiber coupling). The radius of curvature for each of the cylindrical lenses in my system...
