These tables consist of only the commonest host crystals; several Some others exist, which might be considerably less usually employed.
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。
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。

Which geometry, dopant and doping focus from the attain medium are most useful rely on quite a few components. The available pump source (form of laser diode or lamp) as well as envisaged pumping arrangement are essential factors, but the material itself also has some affect. By way of example, titanium–sapphire lasers need to be pumped with higher intensities, for which the form of a transversely cooled rod, operated with reasonably little pump and laser beam diameter, is a lot more proper 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。
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。
The utmost probable doping focus can count strongly on the host content and its fabrication process.
Laser modeling and simulation can be employed to reliably determine the ideal crystal Proportions, doping density And perhaps values of further parameters.
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。
It is obvious that distinct programs result in pretty unique prerequisites on laser get media. Due to this, a broad range of various crystals are made use of, and earning the proper preference is essential for constructing lasers with more info ideal overall performance.

The medium should have a significant transparency (reduced absorption and scattering) from the wavelength regions of pump and laser radiation, and superior optical homogeneity. To some extent, this is dependent upon the caliber of the fabric, based on facts with the fabrication procedure.
