Typical spontaneous emission prices vs. intensity at linewidth 0, 1, 0.01 MHz.Atmosphere 2021, 12,16 ofAccording for the results in Figure 15, when the linewidth with the three-mode CW laser is broadened to 60 MHz, the average spontaneous emission rates increase more than 10 instances at I = 150 W/m2 and exceed these values of the mono-mode laser at linewidth 0 MHz. Such a case significantly enhances the return photons of your sodium laser guide star. As a result, we generate a outcome that the linewidth Myristoleic acid Apoptosis broadening technique is capable of improving the recoil effects on the sodium laser guide star in the case on the multi-mode laser. 6. Conclusions This short Bendazac site article meticulously investigates the effects from the linewidth broadening process around the recoil with the sodium laser guide star. The numerical results show that the linewidth broadening method increases the return photons on the sodium laser guide star. Moreover, to get a laser more than 50 W, the return photons boost greater than one time. Furthermore, this approach won’t make a distinction in the spot sizes with the sodium laser guide star. The optimal values of linewidth broadening are 100 MHz in line with our simulations. This linewidth is capable of achieving wholly optimal average spontaneous emission prices. Our simulations reveal that the mono-mode CW laser at a linewidth significantly less than 1 MHz and much more than 100 MHz cannot obtain high average spontaneous emission prices. So that you can receive the top results, the laser linewidth really should be modulated to be 1 MHz or between 1 and 100 MHz. In addition, the sideband linewidth of re-pumping must be correspondingly broadened. Further evaluation shows that the linewidth broadening approach is capable of weakening the recoil effects from the sodium laser guide star for the multimode laser. A simulated result in the three-mode laser indicates that the average spontaneous emission rates in the sodium laser guide star substantially enhance. A number of cases have established that the linewidth broadening technique is constant together with the actual situation. The existing laser linewidth modulation technique can deliver a reference for laser linewidth broadening. We hope that our results are verified 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.
