These tables contain only the most typical host crystals; many Many others exist, that are a lot less often used.
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
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。
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and in addition the higher-point out lifetime.
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。
A few laser crystal elements happen to be demonstrated in which some saturable absorber substance is incorporated for passive Q switching of the laser.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
For quasi-a few-stage laser attain media or perhaps three-degree get media, one particular normally really should limit the size to a worth and that is also brief for productive pump absorption, as reabsorption outcomes would usually spoil the overall performance. For side pumping, further things to consider come into Perform; besides effective pump absorption, it's important to obtain an acceptable spatial condition from the obtain profile.
Distinct crystalline resources are quite distinctive about their hardness and also other Qualities, which decide with which approaches click here And just how very easily they may be Slash and polished with good quality.
The medium must have a higher transparency (reduced absorption and scattering) during the wavelength regions of pump and laser radiation, and good optical homogeneity. To some extent, this is dependent upon the caliber of the material, based on facts on the fabrication approach.
With that concept, just one does not will need an extra saturable absorber crystal, to ensure that one particular may make a lot more compact Q-switched laser setups with lessen internal parasitic losses. However, unwelcome side effects can also manifest, for example obtaining undesired valence states on the associated ions or energy transfers.
