The commonest laser-Lively unusual earth ions and host media together with some regular emission wavelengths are revealed 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。

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 acquire medium are most useful count on numerous factors. The obtainable pump resource (form of laser diode or lamp) along with the envisaged pumping arrangement are very important elements, but the material itself also has some affect. As an example, titanium–sapphire lasers ought to be pumped with higher intensities, for which the form of a transversely cooled rod, operated with reasonably modest pump and laser beam diameter, is much 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。

Of course, it is rather attractive that a given crystal top quality is generated consistently, Though diverse laser types may have a special sensitivity to materials parameters.

The most possible doping concentration can count strongly over the host material and check here its fabrication technique.

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。

量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

Unique crystalline components are extremely distinctive about their hardness and various Homes, which identify with which solutions And just how very easily they can be Slash and polished with good quality.

The medium ought to have a higher transparency (small absorption and scattering) from the wavelength locations of pump and laser radiation, and superior optical homogeneity. To some extent, this will depend on the quality of the fabric, determined by details in the fabrication process.

With That idea, one won't will need an additional saturable absorber crystal, so that 1 could make extra compact Q-switched laser setups with decreased inside parasitic losses. On the other hand, undesired Unwanted effects may also arise, such as getting unwanted valence states of the involved ions or Strength transfers.
