What Are Some Factors Affecting Linewidth?
Several factors can influence the linewidth of a laser: l Single-frequency operation: As mentioned earlier, achieving true single-mode operation is crucial for the narrowest linewidth. Any deviation towards multi-mode operation broadens the spectrum. l External noise: Environmental factors like vibrations, temperature fluctuations, or even power supply noise can...
