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。
Which geometry, dopant and doping focus with the gain medium are most beneficial depend on various things. The accessible pump source (style of laser diode or lamp) as well as envisaged pumping arrangement are crucial variables, but the fabric alone also has some impact. As an example, titanium–sapphire lasers have to be pumped with significant intensities, for which the shape of a transversely cooled rod, operated with rather little pump and laser beam diameter, is much more appropriate than e.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
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 can be employed to reliably identify the ideal 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。
It is apparent that diverse purposes lead to very various necessities on laser attain media. For this reason, a wide vary of various crystals are applied, and building the appropriate decision is essential for constructing lasers with ideal efficiency.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
The medium ought more info to have a substantial transparency (minimal absorption and scattering) in the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this is dependent upon the caliber of the material, determined by facts in the fabrication procedure.
Utilizing our promoting offer, you may Exhibit your emblem, even further down below your solution description, and these will been viewed by many photonics industry experts.
