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。

为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。

Also, some overall flexibility is missing in experiments if 1 are unable to try out absorbers with distinct thickness or doping focus, one example is, devoid of exchanging the laser crystal alone.

Which geometry, dopant and doping concentration of the get medium are most advantageous depend upon a number of components. The accessible pump resource (sort of laser diode or lamp) and the envisaged pumping arrangement are very important factors, but the material alone also has some influence. By way of example, titanium–sapphire lasers ought to be pumped with large intensities, for which the shape of the transversely cooled rod, operated with click here fairly modest pump and laser beam diameter, is a lot 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。

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。

The maximum achievable doping concentration can rely strongly over the host material and its fabrication technique.

Laser modeling and simulation can be employed to reliably establish the optimum crystal Proportions, doping density And perhaps values of extra 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。

It is apparent that different purposes produce pretty distinctive specifications on laser acquire media. For this reason, a wide selection of different crystals are used, and building the best selection is essential for developing lasers with ideal overall performance.

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。

GWU-Lasertechnik has in excess of thirty years of expertise in distributing laser crystals. Decide on GWU to gain from our extensive expertise and in-industry expertise!

There is certainly an array of crystalline media, which can be grouped in accordance to big atomic constituents and crystalline constructions. Some important teams of crystals are:

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。
