The thermal lens formed in a thermo-optical material as a result of its inhomogeneous
heating, is a well-known phenomenon that has found widespread interest in the last …

Measurement of the thermal mirror caused by laser heating provides direct access to the
optical, thermophysical, and mechanical properties of solid materials. However, the …

Photothermal spectroscopy (PTS) working in the mid-infrared region is an effective
technique for in-situ characterization of the chemical composition of surface contaminants …

Interactions between super bandgap energy photons and semiconductor materials involve
plasma waves in addition to thermal waves, resulting in a strong thermo-electronic coupling …

The sensitivity of photothermal detection relies on both the magnitude of the response of a
sample to excitation and the way the response is sensed. We propose a highly sensitive …

The strong coupling effect of thermal and plasma waves disturbs the accurate
characterization of thermal properties of semiconductors under super bandgap energy …
