The commonest laser-active rare earth ions and host media along with some regular emission wavelengths are proven in the subsequent 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。

This is easy to try and do: just discover the lock icon in front of the URL during the tackle bar and drag that into the bookmark toolbar While using the mouse. In case you find the bookmark entry also very long, you are able to correct-click it to edit the text, e.g. working with "RP Enc" in lieu 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。
活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。
g. a skinny disk. As A different instance, Q-switched lasers get to a better populace density in the higher laser degree and are for that reason more sensitive to quenching effects and energy transfer processes; thus, a lower doping density is often appropriate for these products. For high-electric power lasers, lower doping densities in many cases are used to Restrict the density of heat generation, While slim-disk lasers operate greatest with remarkably doped crystals. Lots of laser solutions tend not to get to the complete effectiveness likely because these information haven't been appropriately worked out.
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。
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
It is clear that various programs lead to really unique specifications on laser get media. Because of this, a broad assortment of different crystals are utilised, and producing the right decision is essential for constructing lasers with the best possible efficiency.

In 2017, we made the whole world’s major Laser Crystal Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with extremely broad emission spectra drives the event of laser diode pumped ultrafast stable-condition lasers. With the increase in pulse Power, peak power, and repetition amount of strong-point out lasers, laser crystals will develop in the direction of larger sized sizes, larger crystal excellent, and controllable important effectiveness.
It might be oriented for near perpendicular incidence in the laser beam, or at Brewster's angle. It could be preset in some strong mount which also acts like a warmth sink. Larger sized crystals are generally utilized for side pumping e.g. with higher-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。
