What is a narrow linewidth laser?
What is a narrow linewidth laser? Narrow linewidth laser, The term “line width” refers to the spectral line width of the laser in the frequency domain, which is usually quantified in terms of the half-peak full width of the spectrum (FWHM). The linewidth is mainly affected by the spontaneous radi...Read More
