The most typical laser-Lively uncommon earth ions and host media together with some regular emission wavelengths are revealed in the subsequent desk:

In this article you are able to submit issues and opinions. So far as they get acknowledged via the author, they can look over this paragraph along with the author’s answer. The author will make a decision on acceptance dependant on specified requirements. In essence, the issue should be of sufficiently broad curiosity.

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。

激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。

Which geometry, dopant and doping concentration on the acquire medium are most advantageous depend upon quite a few elements. The readily available pump supply (style of laser diode or lamp) as well as envisaged pumping arrangement are important elements, but the material alone also has some influence. By way of example, titanium–sapphire lasers need to be pumped with substantial intensities, for which the form of the transversely cooled rod, operated with somewhat compact pump and laser beam diameter, is a lot more ideal than e.

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。

g. a thin disk. As Yet another instance, Q-switched lasers get to a greater population density during the upper laser level and therefore are hence a lot more sensitive to quenching consequences and Electricity transfer procedures; therefore, a lessen doping density is commonly suitable for these equipment. For top-energy lasers, lower doping densities are sometimes utilized to limit the density of heat era, While thin-disk lasers do the job most effective with hugely doped crystals. Several laser goods tend not to reach the complete general performance opportunity because this kind of particulars haven't been effectively labored out.

The host crystal is considerably more than simply a way to repair the laser-active ions at particular positions in Room. here Several properties of the host materials are essential:

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。

For quasi-3-stage laser achieve media as well as 3-degree obtain media, one often should limit the duration to a price that is also shorter for economical pump absorption, as reabsorption effects would normally spoil the efficiency. For aspect pumping, extra things to consider arrive into Participate in; Apart from efficient pump absorption, it's important to acquire a suitable spatial shape of your obtain profile.

For numerous causes, composite crystals are getting to be popular. These have a spatially varying chemical composition and can be created with special styles.

There is a variety of crystalline media, that may be grouped according to important atomic constituents and crystalline constructions. Some important teams of crystals are:

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。
