Which geometry, dopant and doping concentration in the obtain medium are most advantageous rely on a number of factors. The accessible pump source (variety of laser diode or lamp) and also the envisaged pumping arrangement are important things, but the fabric itself also has some impact. For instance, titanium–sapphire lasers ought to be pumped with substantial 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.

A higher surface area excellent is of course crucial. Requirements of floor flatness will often be much better than . This helps to prevent each scattering losses and wavefront distortions which might degrade the laser's beam good quality. Also, scratch and dig requirements

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。

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-a few-level laser achieve media or perhaps three-amount acquire media, a single generally has to Restrict the length to a worth which happens to be also limited for economical pump absorption, as reabsorption results would normally spoil the performance. For side pumping, added things to consider arrive into Engage in; Other than economical more info pump absorption, it's important to obtain a suitable spatial shape of the gain profile.

The medium should have a superior transparency (very low absorption and scattering) inside the wavelength regions of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is dependent upon the quality of the material, based on particulars with the fabrication procedure.

Applying our promoting offer, you'll be able to Display screen your emblem, further under your products description, and these will been observed by quite a few photonics professionals.

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。
