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 �?generally one crystals (monocrystalline optical resources) �?which can be applied as acquire media for stable-state lasers. Usually, These are doped with possibly trivalent uncommon earth ions or changeover metallic ions.

Additionally, some versatility is missing in experiments if one can not try out absorbers with diverse thickness or doping concentration, for instance, with no exchanging the laser crystal by itself.

Which geometry, dopant and doping focus with the acquire medium are most advantageous rely on a number of variables. The readily available pump supply (sort of laser diode or lamp) as well as the envisaged pumping arrangement are important factors, but the fabric itself also has some impact. By way of example, titanium–sapphire lasers must be pumped with higher intensities, for which the shape of a transversely cooled rod, operated with fairly compact pump and laser beam diameter, is much more suitable than e.

活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。

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。

Several laser crystal components have been demonstrated the place some saturable absorber material is integrated for passive Q switching of the laser.

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-a few-degree laser acquire media or even a few-degree gain media, a person typically must Restrict the length to click here a price that is much too quick for efficient pump absorption, as reabsorption results would in any other case spoil the performance. For aspect pumping, more concerns appear into Participate in; Apart from economical pump absorption, it is necessary to acquire an acceptable spatial shape from the achieve profile.

Distinct crystalline products are certainly distinct about their hardness and also other properties, which ascertain with which techniques And just how easily they may be Reduce and polished with high quality.

For many reasons, composite crystals are getting to be well known. These Use a spatially various chemical composition and can be made with Unique styles.

You can find a wide range of crystalline media, which can be grouped according to special atomic constituents and crystalline constructions. Some significant teams of crystals are:
