These tables include only the most typical host crystals; lots of Other individuals exist, which happen to be significantly less regularly employed.
In this article you can post inquiries and reviews. As far as they get recognized from the author, they can surface above this paragraph together with the creator’s remedy. The creator will decide on acceptance based on certain standards. Effectively, The problem have to be of sufficiently wide fascination.
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 flexibility is misplaced in experiments if a single can not try out absorbers with diverse thickness or doping focus, such as, with no exchanging the laser crystal by itself.
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
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。
Not surprisingly, it's very fascinating that a provided crystal top quality is created consistently, Whilst unique laser patterns can have a unique sensitivity to content parameters.
The most achievable doping focus can depend strongly to the host materials and its fabrication system.
The host crystal is far more than just a way to fix the laser-Lively ions at specified positions in space. Quite a few Attributes of the host materials are essential:
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。
Individuals surfaces which can be handed with the laser beam are Typically possibly oriented at Brewster's angle click here or have an anti-reflection coating.
Unique crystalline components are incredibly different regarding their hardness as well as other Houses, which figure out with which procedures and how simply they may be Reduce and polished with high quality.
GWU-Lasertechnik has more than thirty years of expertise in distributing laser crystals. Decide on GWU to get pleasure from our large awareness As well as in-industry experience!
With that concept, a single will not want an extra saturable absorber crystal, to ensure that 1 may make extra compact Q-switched laser setups with lessen inside parasitic losses. On the other hand, undesirable Negative effects might also manifest, for example obtaining undesirable valence states of the included ions or energy transfers.
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。
