**Appendix A**

*Appendix A.1. Optimal Beam Position*

**Figure A1.** Amplitude of the photoacoustic force applied on a cantilever as a function of the laser beam position for two configurations: red—laser beam along the x-axis; blue—laser beam along the y-axis. Where *fn* = 11 kHz, *b* = 50 μm, *h* = 100 μm, and *L* = 3.5 mm, respectively are the resonance frequency, the width, the thickness, and the length of the cantilever.

*Appendix A.2. Quality Factor*

**Figure A2.** Quality factors for viscous damping with squeeze film (top-left panel), support damping (top-right panel), acoustic damping (bottom left panel), and thermoelastic damping (bottom-right panel) as a function of width and thickness of a cantilever. Cantilever's fundamental resonance frequency: 11 kHz, gap between support and cantilever: *d* = 10 μm.

**Figure A3.** Quality factors for squeeze film (top-left panel), viscous damping originating from the top and bottom side of a cantilever (top-right panel), viscous damping originating from left and right side of a cantilever (bottom left panel) and Reynolds number (bottom-right panel) as a function of width and thickness of a cantilever. Cantilever's fundamental resonance frequency: 11 kHz, gap between support and cantilever: *d* = 10 μm.

*Appendix A.3. Thermal Noise*

**Figure A4.** Thermal noise as a function of width and thickness of a cantilever. Cantilever's fundamental resonance frequency: 11 kHz (**a**) and 60 kHz (**b**), gap between support and cantilever: *d* = 10 μm.
