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 straightforward to carry out: just find the lock icon in front of the URL during the deal with bar and drag that into the bookmark toolbar With all the mouse. Just in case you locate the bookmark entry also very long, you can proper-click on it to edit the textual content, e.g. working with "RP Enc" instead 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。
A large floor high quality is naturally vital. Specs of surface area flatness in many cases are much better than . This allows to avoid each scattering losses and wavefront distortions which may degrade the laser's beam top quality. Furthermore, scratch and dig specs
The utmost probable doping concentration can count strongly about the host material and its fabrication system.
The host crystal is a great deal more than just a means to fix the laser-Energetic ions at selected positions in space. Quite a few Houses of the host content are very important:
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 numerous factors, composite crystals have become well-known. These Have got a spatially varying chemical composition and may be built with Exclusive styles.
It could be oriented for in the vicinity of perpendicular incidence of your laser beam, or at Brewster's angle. It might be fastened in a few sound mount which also acts as being a warmth sink. Much larger crystals usually are employed for side pumping e.g. with high-ability diode bars.
