The most typical laser-Energetic exceptional earth ions and host media together with some normal emission wavelengths are shown in the following table:
Right here you may submit queries and reviews. As far as they get accepted through the writer, they're going to look over this paragraph together with the creator’s answer. The creator will determine acceptance dependant on specified standards. In essence, the issue has to be of sufficiently wide curiosity.
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 in the acquire medium are most advantageous rely on numerous elements. The obtainable pump source (type of laser diode or lamp) and the envisaged pumping arrangement are crucial components, but the material itself also has some impact. One example is, titanium–sapphire lasers should be pumped with large intensities, for which the shape of a transversely cooled rod, operated with rather modest pump and laser beam diameter, is 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。
Certainly, it's very appealing that a given crystal high-quality is generated constantly, Even though unique laser patterns might have a distinct sensitivity to product parameters.
g. a skinny disk. As Yet another case in point, Q-switched lasers arrive at a higher populace density in the upper laser amount and so are consequently extra delicate to quenching outcomes and energy transfer processes; as a result, a decrease doping density is often appropriate for these gadgets. For high-electricity lasers, decrease doping densities will often be utilized to Restrict the density of warmth technology, Despite the fact that slender-disk lasers work most effective with remarkably doped crystals. A lot of laser items do not get to the total performance opportunity for the reason that these particulars haven't been correctly labored out.
The host crystal is considerably more than simply a means to repair the laser-active ions at specified positions in House. A variety of properties in the host substance are crucial:
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 apparent that various programs produce very various needs on laser attain media. Because of this, a broad range of various crystals are used, and earning the right choice is important for setting up lasers with optimum performance.

For several good reasons, composite crystals have become preferred. These Use a click here spatially various chemical composition and can be made with Distinctive designs.
There is a wide range of crystalline media, which may be grouped according to special atomic constituents and crystalline constructions. Some vital 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。
