Blog Article

These tables have only the commonest host crystals; numerous Other folks exist, that are considerably less frequently utilized.

In this article you'll be able to submit inquiries and comments. As far as they get accepted because of the creator, they'll look previously mentioned this paragraph along with the author’s answer. The writer will choose acceptance based upon specific requirements. Primarily, the issue must be of adequately broad desire.

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。

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 concentration of the acquire medium are most advantageous count on several things. The out there pump resource (kind of laser diode or lamp) along with the envisaged pumping arrangement are essential elements, but the fabric alone also has some influence. For instance, titanium–sapphire lasers ought to be pumped with significant intensities, for which the form of the transversely cooled rod, operated with comparatively small 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。

Obviously, it is rather appealing that a given crystal high-quality is generated persistently, Though various laser designs may have a special sensitivity to product parameters.

亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。

Laser modeling and simulation may be used to reliably figure out the the best possible crystal dimensions, 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。

For quasi-3-level laser get media as well as three-stage acquire media, one typically has to Restrict the length to a price that is far too brief for successful pump absorption, as reabsorption effects would usually spoil the functionality. For facet pumping, additional things to consider occur into Perform; Moreover economical pump absorption, it is vital to get an acceptable spatial condition click here of your gain profile.

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 30 many years of experience in distributing laser crystals. Pick GWU to take advantage of our large know-how As well as in-discipline practical experience!

There is an array of crystalline media, which may be grouped according to special atomic constituents and crystalline constructions. Some significant 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。
