Derivation of the schawlow–townes linewidth
WebA detailed experimental and theoretical investigation on the evolution of linewidth Av(I) function of injection current for different structures of semiconductor lasers has been undertaken. Linewidth shows a continuous transition and tends asymptotically on either side to Schawlow-Townes inverse power behaviours. In a small current zone at … WebOct 2, 2024 · Laser linewidth is of central importance in spectroscopy, frequency metrology, and all applications of lasers requiring high coherence. It is also of fundamental importance, because the Schawlow-Townes laser linewidth limit is of quantum origin. Recently, a theory of stimulated Brillouin laser (SBL) linewidth has been reported.
