The most typical laser-active rare earth ions and host media along with some common emission wavelengths are shown in the following desk:
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
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 perform: just locate the lock icon before the URL while in the tackle bar and drag that for the bookmark toolbar Together with the mouse. In the event you find the bookmark entry too extensive, you could suitable-click on it to edit the text, e.g. applying "RP Enc" in lieu of "RP Photonics Encyclopedia".
GWU offers all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) using a wide assortment of specifications. Besides the very well-proven components, revolutionary crystals with outstanding Houses like Yb:CALGO can open new horizons for demanding laser apps. Irrespective of whether specific items for R & D functions are necessary or Expense-successful quantities in little, medium or large batches with in-time supply for the generation line are needed: GWU’s committed service helps you to find the ideal Main components to your software.
A superior surface area excellent is obviously significant. Technical specs of surface flatness are frequently a lot better than . This allows to prevent each scattering losses and wavefront distortions which might degrade the laser's beam quality. In addition, scratch and dig specifications
The most probable doping focus can count strongly over the host material and its fabrication technique.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。

For quasi-three-amount laser get media and even three-amount obtain media, a single typically really should Restrict the duration to a price that's too brief for effective pump absorption, as reabsorption outcomes would otherwise spoil the efficiency. For side pumping, added factors arrive into play; Other than successful pump absorption, it is vital to acquire an acceptable spatial form of the acquire profile.
Different crystalline elements are incredibly different regarding their hardness together with other Houses, which figure out with more info which procedures and how simply they may be Reduce and polished with high quality.
For several motives, composite crystals are getting to be preferred. These Use a spatially various chemical composition and may be produced with special styles.
It might be oriented for around perpendicular incidence from the laser beam, or at Brewster's angle. It may be mounted in a few reliable mount which also functions being a heat sink. Greater crystals are frequently employed for facet pumping e.g. with high-electrical power diode bars.
