A three panel figure showing microlaser characteristics during dynamic compression by an atomic force microscope. (a) Lasing spectra acquired during a push and release experiment, where the force applied by the AFM onto the microlaser is linearly increased from 0 nN to 7 nN and then released back to 0 nN. The spectra are normalized and vertically offset to show the shift and broadening of the lasing modes. (b) Fitted center position of the lasing modes labelled in (a), plotted over the time of the experiment. Two time points right after the microlaser made contact with the beaded tip of the AFM are excluded from the plot due to strong mode splitting. (c) Fitted FWHM (symbols, left axis) of the 4 laser modes shown in (b) and the measured applied force (pink solid line, right axis) as function of time. The resolution limit of the spectrometer is about 50 pm.
Very happy to finalize a few projects after a busy year, starting with a pre-print of Melisa's work on #flexible #microlasers made from #elastomers! A great material to prepare soft microlasers to measure biological #forces. #biophotonics #biosensing arxiv.org/abs/2512.22707
