The most typical laser-active unusual earth ions and host media together with some common emission wavelengths are revealed in the next table:

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。

Laser crystals are optical crystals �?usually one crystals (monocrystalline optical components) �?which happen to be made use of as get media for reliable-point out lasers. Most often, They may be doped with possibly trivalent exceptional earth ions or changeover metallic ions.

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 focus of the gain medium are most advantageous depend on several factors. The accessible pump source (style of laser diode or lamp) as well as envisaged pumping arrangement are crucial variables, but the material alone also has some affect. For instance, titanium–sapphire lasers ought to be pumped with significant intensities, for which the form of the transversely cooled rod, operated with reasonably tiny pump and laser beam diameter, is a lot more acceptable 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。

A superior surface top quality is obviously crucial. Technical specs of surface flatness tend to be a lot better than . This will help to stop both equally scattering losses and wavefront distortions that may degrade the laser's beam quality. In addition, scratch and dig requirements

探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。

A handful of click here laser crystal resources happen to be demonstrated where by some saturable absorber materials is integrated for passive Q switching of the laser.

For quasi-a few-stage laser obtain media or even 3-level achieve media, 1 normally has to Restrict the size to a value that's as well limited for efficient pump absorption, as reabsorption results would normally spoil the efficiency. For facet pumping, extra criteria come into Enjoy; Other than economical pump absorption, it is important to obtain an appropriate spatial form on the get profile.

Diverse crystalline supplies are really distinct about their hardness along with other Houses, which identify with which solutions And the way simply they may be cut and polished with good quality.

For many explanations, composite crystals are becoming well known. These Have got a spatially various chemical composition and may be produced with special shapes.

It may be oriented for close to perpendicular incidence from the laser beam, or at Brewster's angle. It can be fastened in certain reliable mount which also acts being a heat sink. Bigger crystals are often useful for aspect pumping e.g. with large-energy 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。
