WebDec 1, 2024 · β 2, β 3, γ are coefficients of GVD, TOD and nonlinear respectively, ω 0 is the carrier frequency and T R is the Raman resonant time constant. Considering the Ytterbium-doped fiber with the central wavelength λ 0 = 1060 nm [33], the reference values are β 2 = 23 fs 2 / mm, β 3 = 63.8 fs 2 / mm, and γ = 4.7 × 10 − 6 w − 1 / mm − 1. WebFeb 8, 2016 · The GVD and TOD at 1150 nm are determined to be 4420 fs 2 and −55900 fs 3, respectively. To verify these values, we calculated the pule envelope of the fundamental before the compression by applying the GVD and TOD values to the transform limited pulse obtained from the Fourier transform of the fundamental pulse spectrum.
