These tables have only the commonest host crystals; many Other folks exist, that are considerably less routinely utilized.
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。
Laser crystals are optical crystals �?ordinarily single crystals (monocrystalline optical components) �?which are made use of as acquire media for reliable-point out lasers. In most cases, They may be doped with both trivalent unusual earth ions or transition metal ions.
In addition, some versatility is missing in experiments if 1 are not able to Check out absorbers with distinctive thickness or doping concentration, by way of example, devoid of exchanging the laser crystal alone.
Which geometry, dopant and doping concentration of the gain medium are most advantageous count on several things. The out there pump resource (form of laser diode or lamp) along with the envisaged pumping arrangement are essential elements, but the fabric by itself also has some affect. For instance, titanium–sapphire lasers have to be pumped with significant intensities, for which the form of the transversely cooled rod, operated with fairly compact pump and laser beam diameter, is much more appropriate than e.
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。
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。

For quasi-three-amount laser achieve media or perhaps a few-degree attain media, one particular frequently really should limit the size to a value and that is as well small for economical pump absorption, as reabsorption results would if not spoil the efficiency. For facet pumping, check here additional issues appear into play; Moreover efficient pump absorption, it is vital to get an appropriate spatial form with the attain profile.

The medium should have a superior transparency (minimal absorption and scattering) from the wavelength regions of pump and laser radiation, and good optical homogeneity. To some extent, this will depend on the quality of the fabric, determined by aspects with the fabrication method.
Working with our promoting offer, you'll be able to Display screen your logo, even more below your solution description, and these will been viewed by many photonics specialists.
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。
