WebAn alternative method to measure the Q-factor of a resonator is to measure the ring-down time. Upon switching off the drive signal of a resonator and because of dissipation, the free-decaying resonance amplitude follows an exponential law: A (t) = A0.exp (-t/τ), where the time constant, τ , in the exponential argument is directly proportional ... Web1 day ago · In Fig. 6 (b), the measurements of FWHM(2D) show new dependance that can be approximated by a parabolic trend centered around the CNP. In Fig. 6 (a) and (b), the combination of the intensity and the FWHM show that the 2D mode tends to stiffen (soften) significantly for slight (stronger) doping for both electrons and holes, which is clearly ...

WebRocking Curve. RC measurement reveals broadening of the diffraction peaks. The increase in the peak widths can be caused by: Mosaicity (misorientation of crystallites) Strain. … Webreliable detection and measurement. This point normally is the reason for preferring HPGe over sodium iodide detectors for low-level measurements, even though the sodium iodide is likely to have a greater efficiency of counting.

Webthe linewidth (FWHM) is proportional to the square of the resonator bandwidth divided by the output power (assuming that there are no parasitic resonator losses). The article on the Schawlow–Townes linewidth contains a more practical form of the equation.. The Schawlow–Townes limit is usually difficult to reach in reality, as there are various … WebFeb 27, 2015 · The FWHM number is very important if you plan to use the structure as a sensor, specifically, to measure nearby refractive index changes. The thinner the peak the better signal to noise ratio... WebJul 18, 2011 · As for FWHM measurements and how they correlate with guide RMS. Guide RMS is one factor out of many that affect blur.
