Comment to Noise investigation - Tama-sized sapphire sample sitting on blocks (Click here to view original report: 241)

I made a calculation that might explain why I couldn't see any absorption signal.

The cross point between pump and probe changes position when there is a thick sapphire sample.

Details are in the attached slide.

This might also explain why in my simulations the simulated scan shows a thicker sample than the measured scan. I will include this effect in the simulations and check the result.
