These tables incorporate only the commonest host crystals; numerous Other folks exist, which are significantly less usually made use of.
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。

This is not hard to complete: just discover the lock icon in front of the URL from the handle bar and drag that to the bookmark toolbar With all the mouse. In the event you discover the bookmark entry far too extensive, you can correct-click it to edit the text, e.g. making use of "RP Enc" rather than "RP Photonics Encyclopedia".
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 high surface area quality is needless to say significant. Requirements of floor flatness tend to be much better than . This assists to stay away from both scattering losses and wavefront distortions which can degrade the laser's beam high-quality. In addition, scratch and dig technical specs
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 couple of laser crystal products are demonstrated where by some saturable absorber content is incorporated for passive Q switching of the laser.

It is obvious that distinct applications lead to pretty unique necessities on laser achieve media. Because of this, a broad vary of various crystals are utilized, and making website the ideal alternative is essential for developing lasers with ideal efficiency.
Diverse crystalline materials are certainly distinct about their hardness along with other Attributes, which establish with which methods And the way easily they are often Slice and polished with good quality.
The medium ought to have a high transparency (reduced absorption and scattering) inside the wavelength regions of pump and laser radiation, and excellent optical homogeneity. To some extent, this is determined by the caliber of the material, determined by particulars from the fabrication procedure.
It might be oriented for in close proximity to perpendicular incidence with the laser beam, or at Brewster's angle. It might be fixed in some solid mount which also acts as being a heat sink. Bigger crystals are generally utilized for aspect pumping e.g. with large-electricity diode bars.
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。
