The most typical laser-Energetic scarce earth ions and host media along with some regular emission wavelengths are shown in the next table:

Below you could submit questions and responses. As far as they get accepted because of the writer, they are going to appear above this paragraph together with the creator’s respond to. The writer will settle on acceptance depending on specified criteria. Basically, The difficulty needs to be of sufficiently broad curiosity.

This is straightforward to do: just discover the lock icon before the URL in the handle bar and drag that on the bookmark toolbar With all the mouse. In case you locate the bookmark entry far too extended, you could suitable-simply click it to edit the textual content, e.g. working with "RP Enc" as an alternative 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。

激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。

The utmost probable doping concentration can rely strongly on the host product 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-3-degree laser get click here media or simply 3-stage attain media, 1 frequently ought to Restrict the length to a value which can be far too small for economical pump absorption, as reabsorption effects would in any other case spoil the functionality. For aspect pumping, further criteria come into Enjoy; Apart from productive pump absorption, it's important to obtain an acceptable spatial form in the gain profile.

Diverse crystalline elements are very distinct relating to their hardness and other Homes, which identify with which procedures And exactly how conveniently they can be Lower and polished with high quality.

For many motives, composite crystals are becoming preferred. These Use a spatially different chemical composition and might be made with Distinctive shapes.

It might be oriented for in the vicinity of perpendicular incidence on the laser beam, or at Brewster's angle. It could be mounted in certain solid mount which also acts for a heat sink. Larger crystals are frequently useful for facet pumping e.g. with higher-electricity 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。
