Webb1 maj 2024 · The modal peak gain of LD1 is larger than LD2, which can be explained by the smaller inhomogeneous broadening of LD1. The lines are linear fitting of the experimental data of mode peak gain, which gives the differential gain of the LDs. The differential gain of LD1 and LD2 are 3.53 and 2.08 cm/kA, respectively.

Webb5 mars 2015 · In gas lasers, where the atoms or molecules are free to move, the inhomogeneous broadening is due to the Doppler effect, for which a molecule moving with velocity v in a field of frequency ω and wave vector k experiences an effective frequency ω ′ = ω − k · v [8]. There are a number of effects which control spectral line shape. A spectral line extends over a range of frequencies, not a single frequency (i.e., it has a nonzero linewidth). In addition, its center may be shifted from its nominal central wavelength. There are several reasons for this broadening and shift. These reasons may be divided into two general categories – broadening due to local conditions and broadening due to extended conditions. Broadening due to local conditions is du…
