The commonest laser-Energetic uncommon earth ions and host media along with some common emission wavelengths are demonstrated 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。
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。

This is easy to perform: just locate the lock icon in front of the URL from the handle bar and drag that towards the bookmark toolbar Along with the mouse. In case you find the bookmark entry much too lengthy, it is possible to right-click it to edit the text, e.g. making use of "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。
Needless to say, it is extremely desirable that a given crystal quality is manufactured consistently, Though distinct laser styles might have a distinct sensitivity to material parameters.
g. a skinny disk. As Yet another case in point, Q-switched lasers attain an increased inhabitants density in the upper laser stage and are as a result additional delicate to quenching effects and here Strength transfer processes; thus, a lessen doping density is often appropriate for these gadgets. For high-electricity lasers, decreased doping densities will often be utilized to Restrict the density of warmth technology, although slender-disk lasers do the job most effective with really doped crystals. Lots of laser solutions do not get to the whole effectiveness likely due to the fact this kind of details haven't been correctly labored out.
The host crystal is considerably more than simply a means to fix the laser-Energetic ions at selected positions in space. A variety of Houses of the host materials are very important:
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 different applications result in really diverse demands on laser achieve media. This is why, a broad assortment of different crystals are utilized, and creating the proper option is important for setting up lasers with optimum overall performance.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
GWU-Lasertechnik has more than 30 many years of knowledge in distributing laser crystals. Opt for GWU to benefit from our wide understanding and in-subject working experience!
It could be oriented for around perpendicular incidence with the laser beam, or at Brewster's angle. It may be fastened in a few stable mount which also functions being a heat sink. Larger sized crystals are generally employed 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。
