Abstract
[en] This thesis presents the design, assembly, and characterization of a custom-built Scanning Laser Microscope (SLM). The capabilities of the setup are demonstrated on superconducting coplanar waveguide resonators. Furthermore, the methodology is extended to achieve time-resolved reconstruction of the sample's thermal response through an inverse Fourier transform using multi-harmonic lock-in detection. To support the experimental findings, the underlying physics, including transmission line theory, superconductivity, and thermal modeling, is thoroughly developed, alongside a detailed description of the experimental instrumentation.
