These tables have only the most typical host crystals; lots of Some others exist, that happen to be less usually used.
Below it is possible to post issues and feedback. In terms of they get accepted with the writer, they can appear higher than this paragraph together with the author’s respond to. The author will choose acceptance depending on specified criteria. In essence, The difficulty needs to be of adequately broad curiosity.
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。
This is not difficult to complete: just discover the lock icon before the URL within the tackle bar and drag that to the bookmark toolbar With all the mouse. In case you discover the bookmark entry far too long, it is possible to ideal-simply click it to edit the text, e.g. utilizing "RP Enc" as opposed to "RP Photonics Encyclopedia".
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。
Of course, it is vitally attractive that a supplied crystal good quality is made continually, Whilst unique laser types can have a different sensitivity to substance 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。
A handful of laser crystal resources have been demonstrated where by some saturable absorber materials is integrated for passive Q switching of the laser.
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-three-amount laser acquire media or even 3-level attain media, one particular frequently really should limit the size to a worth that's too small for more info economical pump absorption, as reabsorption results would if not spoil the functionality. For facet pumping, extra things to consider occur into Perform; Aside from productive pump absorption, it is important to obtain a suitable spatial shape in the achieve profile.
Various crystalline elements are incredibly unique regarding their hardness and other Homes, which determine with which approaches And exactly how effortlessly they are often Slash and polished with good quality.
GWU-Lasertechnik has more than 30 many years of expertise in distributing laser crystals. Decide on GWU to benefit from our broad understanding and in-area knowledge!
There's an array of crystalline media, that may be grouped according to big atomic constituents and crystalline constructions. Some essential groups 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。
