Background:

Accurate measurement of thermal diffusion properties at interfaces is crucial for understanding heat transfer in various materials.
Conventional methods like pump-probe techniques can be sensitive to environmental factors such as vibrations and misalignments.

Purpose of the Study:

To develop and validate a novel, simpler technique for measuring the thermal diffusion properties of interfaces.
To establish a method that is less sensitive to experimental disturbances compared to existing techniques.

Main Methods:

Utilizing self-induced surface thermal lensing with a single laser beam to probe thermal diffusion.
Analyzing the time evolution of the reflected laser beam to extract heat diffusion information away from the interface.
