Such a case considerably enhances the return photons in the sodium laser guide star. Therefore, we make a outcome that the linewidth broadening strategy is capable of enhancing the recoil effects of the sodium laser guide star in the case of your multi-mode laser. six. Conclusions This short article very carefully investigates the effects with the linewidth broadening system on the recoil in the sodium laser guide star. The numerical final results show that the linewidth broadening method increases the return photons in the sodium laser guide star. Furthermore, to get a laser more than 50 W, the return photons enhance greater than one time. Moreover, this technique is not going to make a distinction within the spot sizes of the sodium laser guide star. The optimal values of linewidth broadening are one hundred MHz in line with our simulations. This linewidth is capable of attaining wholly optimal typical spontaneous emission prices. Our simulations reveal that the mono-mode CW laser at a linewidth significantly less than 1 MHz and more than 100 MHz can not receive high typical spontaneous emission rates. So as to obtain the top results, the laser linewidth must be modulated to become 1 MHz or amongst 1 and 100 MHz. Moreover, the sideband linewidth of re-pumping should be correspondingly broadened. Additional analysis shows that the linewidth broadening method is capable of weakening the recoil effects of the sodium laser guide star for the multimode laser. A simulated result on the three-mode laser indicates that the typical spontaneous emission rates of the sodium laser guide star significantly increase. Many cases have proven that the linewidth broadening system is constant using the actual scenario. The current laser linewidth modulation process can present a reference for laser linewidth broadening. We hope that our benefits are established by experiments.Author Contributions: Conceptualization, X.L. and X.Q.; methodology, X.L.; application, 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.
