What experience has anyone had with laser beam spectral line width?
Is it correct that there is some broadening of the laser wavelength spectrum with shorter beam pulse lengths?
Has anyone measured this effect or know what their laser spectral pulse is?
At Herstmonceux we use a narrow band filter for daylight ranging, but we are concerned that we cannot select the narrowest filter possible because we must consider the spectral width of our kHz laser.
