Average spontaneous emission rates vs. intensity at linewidth 0, 1, 0.01 MHz.Atmosphere 2021, 12,16 ofAccording for the outcomes in Figure 15, when the linewidth on the three-mode CW laser is broadened to 60 MHz, the average spontaneous emission rates raise more than ten occasions at I = 150 W/m2 and exceed these values of your mono-mode laser at linewidth 0 MHz. Such a case significantly enhances the return photons with the sodium laser guide star. Thus, we create a result that the linewidth broadening approach is capable of enhancing the recoil effects with the sodium laser guide star in the case from the multi-mode laser. 6. Conclusions This short article very carefully investigates the effects of the linewidth broadening approach around the recoil of the sodium laser guide star. The numerical outcomes show that the linewidth broadening approach increases the return photons from the sodium laser guide star. Additionally, for any laser more than 50 W, the return photons raise more than one particular time. In addition, this system won’t make a distinction within the spot sizes of your sodium laser guide star. The optimal values of linewidth broadening are one hundred MHz according to our simulations. This linewidth is capable of attaining wholly optimal average spontaneous emission prices. Our simulations reveal that the mono-mode CW laser at a linewidth much less than 1 MHz and more than one hundred MHz can not acquire higher typical spontaneous emission rates. As a way to receive the best benefits, the laser linewidth must be modulated to be 1 MHz or among 1 and 100 MHz. Also, the sideband linewidth of re-pumping must be correspondingly broadened. Additional evaluation shows that the linewidth broadening system is capable of weakening the recoil effects from the sodium laser guide star for the multimode laser. A simulated outcome of your three-mode laser indicates that the typical spontaneous emission rates from the sodium laser guide star substantially Nipecotic acid Protocol improve. Many instances have confirmed that the linewidth broadening strategy is constant with the actual circumstance. The current laser linewidth modulation approach can deliver a reference for laser linewidth broadening. We hope that our benefits are confirmed by experiments.Author Contributions: Conceptualization, X.L. and X.Q.; methodology, X.L.; software program, D.L.; validation, C.F. and H.Y.; formal analysis, R.H. and C.C.; investigation, X.L. and C.C.; writing–original draft preparation, X.L.; writing–review and editing, R.H.; visualization, X.L.
