Webb5 juni 2012 · The laser linewidth is an important quantity. For example, it determines the fundamental limit of operation of an active ring laser gyroscope. The first fully quantized derivation of the laser linewidth general enough to include even the semiconductor laser linewidth problem utilized a quantum noise operator approach, and is presented in … Webb2 feb. 2024 · To calculate the laser linewidth, we use the following equation: Δν = (π h v Γ²)/P. And follow these steps: Multiply the fundamental frequency ( v) of the laser by the square of the cavity linewidth ( Γ ). Multiply the result by the constant πh, where h is the Planck constant. Divide by P, the power of the laser mode.
