These tables comprise only the most common host crystals; numerous Other individuals exist, which might be less frequently used.

Here you are able to submit questions and comments. In terms of they get approved from the author, they'll appear higher than this paragraph along with the author’s remedy. The writer will decide on acceptance dependant on selected requirements. Effectively, The problem must 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 of your attain medium are most beneficial rely on several components. The offered pump source (style of laser diode or lamp) as well as the envisaged pumping arrangement are important variables, but the fabric by itself also has some impact. By way of example, titanium–sapphire lasers must be pumped with superior intensities, for which the form of the transversely cooled rod, operated with fairly smaller pump and laser beam diameter, is more proper than e.

A substantial floor excellent is of course essential. Specs of surface flatness tend to be better than . This helps to avoid each scattering losses and wavefront distortions which may degrade the laser's beam high quality. In addition, scratch and dig requirements

The maximum attainable doping focus can depend strongly about the host product and its fabrication technique.

The host crystal is much more than just a way to repair the laser-Energetic ions at selected positions in House. A number of properties from 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。

Those surfaces which might be passed because of the laser beam are Typically possibly oriented at Brewster's angle or have an anti-reflection coating.

For different causes, composite crystals are becoming well-known. These Have got a spatially varying chemical composition and can be created with more info Unique designs.

You can find a wide range of crystalline media, which can be grouped in accordance to big atomic constituents and crystalline buildings. 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。
