激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
In addition, some versatility is shed in experiments if 1 are not able to Check out absorbers with unique thickness or doping focus, such as, without exchanging the laser crystal itself.
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions in addition to the upper-condition life span.
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
Laser modeling and simulation can be used to reliably ascertain the optimum crystal Proportions, doping density and possibly values of added parameters.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
For quasi-three-amount laser acquire media or perhaps a few-degree attain media, just one usually has to Restrict the length to a price that is far too brief for economical pump absorption, as reabsorption results would if not spoil the functionality. For facet pumping, extra things to consider come into Perform; Moreover efficient pump absorption, it Laser Crystal is necessary to acquire an acceptable spatial condition from the obtain profile.
