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 �?normally one crystals (monocrystalline optical components) �?which are utilised as gain media for strong-point out lasers. Generally, These are doped with possibly trivalent uncommon earth ions or transition steel ions.

Which geometry, dopant and doping concentration of the gain medium are most useful count on quite a few things. The available pump resource (form of laser diode or lamp) along with the envisaged pumping arrangement are essential elements, but the fabric by itself also has some impact. One example is, titanium–sapphire lasers should be pumped with substantial intensities, for which the shape of a transversely cooled rod, operated with relatively smaller pump and laser beam diameter, is more ideal than e.

A large floor good quality is of course significant. Specs of floor flatness will often be much better than . This assists to stop equally scattering losses and wavefront distortions which often can degrade the laser's beam high-quality. Additionally, scratch and dig specifications

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。

The host crystal is a great deal more than simply a means to fix the laser-active ions at specified positions in House. Several Attributes of the host material are essential:

热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

These surfaces which are handed through the laser beam are Usually possibly oriented at Brewster's angle or have an anti-reflection coating.

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。

The medium must have a high transparency (small absorption and scattering) while in the wavelength regions of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is dependent upon the quality of the material, based on specifics of your get more info fabrication approach.

With That idea, a person does not need yet another saturable absorber crystal, to make sure that a person may perhaps make additional compact Q-switched laser setups with decrease inner parasitic losses. Nevertheless, unwelcome side effects could also arise, including obtaining undesired valence states in the associated ions or Strength transfers.

人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
