The commonest laser-Lively unusual earth ions and host media together with some standard emission wavelengths are revealed in the next table:

These ions allow the crystal to amplify light-weight within the laser wavelength by way of stimulated emission, when Strength is supplied into the crystal through absorption of pump light (�?optical pumping

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（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。

The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions as well as the upper-point out lifetime.

活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。

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 may be used to reliably determine the ideal crystal Proportions, doping density And maybe values of additional parameters.

热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

For quasi-three-amount laser acquire media or even a more info few-level attain media, one particular frequently really should limit the duration to a value and that is also shorter for productive pump absorption, as reabsorption consequences would or else spoil the general performance. For side pumping, added considerations appear into Participate in; Aside from economical pump absorption, it is vital to get an acceptable spatial condition of your gain profile.

Different crystalline elements are incredibly different regarding their hardness and other Homes, which determine with which approaches And exactly how very easily they are often Slash and polished with high quality.

For many explanations, composite crystals have gotten common. These Have a very spatially varying chemical composition and will be manufactured with special styles.

It may be oriented for close to perpendicular incidence in the laser beam, or at Brewster's angle. It could be fastened in a few reliable mount which also functions as a warmth sink. Larger crystals are usually used for facet pumping e.g. with superior-ability diode bars.
