These tables incorporate only the commonest host crystals; several Many others exist, which can be considerably less routinely utilized.
Listed here you could post concerns and reviews. In terms of they get accepted through the author, they are going to look earlier mentioned this paragraph together with the author’s solution. The author will decide on acceptance based on sure conditions. In essence, the issue need to be of adequately wide 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。

This is not hard to perform: just locate the lock icon before the URL inside the handle bar and drag that towards the bookmark toolbar Along with the mouse. In case you find the bookmark entry too extended, you could correct-click it to edit the text, e.g. employing "RP Enc" in place of "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。
Obviously, it is very attractive that a specified crystal excellent is made constantly, Even though distinctive laser models can have another sensitivity to substance parameters.
The most attainable doping concentration can rely strongly on the host substance and its fabrication method.
The host crystal is a great deal more than just a way to repair the laser-Lively ions at particular positions in Room. A variety of Attributes in the host substance are crucial:
蓝宝�?柱面�?球罩 偏振�?棱镜 红外光学元件 反射�?光学窗口 非球面镜 波片 分光�?制造能力
It is clear that distinctive purposes result in extremely various needs on laser obtain media. For that reason, a broad vary of various crystals are utilised, and generating the best selection is essential for developing lasers with ideal overall performance.

For many factors, composite crystals are becoming preferred. These Use a spatially various chemical composition and can be built with Distinctive designs.
It could be oriented for near perpendicular incidence of the laser beam, or at Brewster's angle. It can be fixed in some solid mount Laser Crystal which also functions as being a heat sink. Bigger crystals are usually used for facet pumping e.g. with significant-electric power diode bars.
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。
