Such a case significantly enhances the return photons of your sodium laser guide star. Therefore, we create a result that the linewidth broadening technique is capable of enhancing the recoil effects from the sodium laser guide star inside the case on the multi-mode laser. 6. Conclusions This article very carefully investigates the effects in the linewidth broadening technique around the recoil with 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, to get a laser more than 50 W, the return photons increase more than one time. Moreover, this method will not make a distinction within the spot sizes in the sodium laser guide star. The optimal values of linewidth broadening are 100 MHz in line with our simulations. This linewidth is capable of reaching wholly optimal average spontaneous emission rates. Our simulations reveal that the mono-mode CW laser at a linewidth significantly less than 1 MHz and more than one hundred MHz cannot obtain higher typical spontaneous emission prices. In order to acquire the very best benefits, the laser linewidth should be modulated to be 1 MHz or involving 1 and 100 MHz. In addition, the sideband linewidth of re-pumping need to be correspondingly broadened. Additional evaluation shows that the linewidth broadening system is capable of weakening the recoil effects with the sodium laser guide star for the multimode laser. A simulated outcome in the three-mode laser indicates that the average spontaneous emission rates of the sodium laser guide star considerably enhance. Many circumstances have verified that the linewidth broadening strategy is consistent using the actual situation. The existing laser linewidth modulation strategy can give a reference for laser linewidth broadening. We hope that our benefits are verified by experiments.Author Contributions: Conceptualization, X.L. and X.Q.; methodology, X.L.; computer software, D.L.; validation, C.F. and H.Y.; formal evaluation, 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.
