dear all, a question for your kind help. I take up material science research, laser materials to be detail. Now hope to otbain the power fourier transform spectrum of the laser emission spectrum in order to analyze the information on oscillation cavity. will you please give me some suggestions?
PS: my knowledge is only that the unit of x-axis in the emission spectrum should be transferred to the inverse of length unit (e.g. cm-1 or um-1), but I have no idea of the following steps.

See Analysis: Advanced Math...> Fast Fourier Transform (FFT) in the Origin reference (Help> Origin). For power spectrum choose Spectrum = Power on the Operation tab of the FFT dialog. See the Origin and FFT section of the reference for the effects of sampling. (For best results the number of data points should be a power of two.)
