These tables consist of only the commonest host crystals; a lot of Many others exist, that happen to be less usually applied.
These ions enable the crystal to amplify light-weight with the laser wavelength by way of stimulated emission, when Power is equipped for the crystal via absorption of pump gentle (�?optical pumping
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。
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 concentration of the acquire medium are most advantageous depend on several factors. The available pump resource (style of laser diode or lamp) as well as envisaged pumping arrangement are very important variables, but the material alone also has some impact. For instance, titanium–sapphire lasers have to be pumped with superior intensities, for which the form of the transversely cooled rod, operated with somewhat 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。
Naturally, it's very appealing that a provided crystal quality is produced continuously, Whilst different here laser models may have a different sensitivity to substance parameters.
The maximum attainable doping concentration can rely strongly on the host content and its fabrication method.
The host crystal is a great deal more than simply a means to fix the laser-Energetic ions at selected positions in space. Several Houses of your 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。
It is apparent that distinct apps cause incredibly unique prerequisites on laser attain media. Due to this, a wide array of various crystals are utilised, and producing the ideal choice is important for setting up lasers with optimum performance.

The medium must have a higher transparency (low absorption and scattering) from the wavelength regions of pump and laser radiation, and superior optical homogeneity. To some extent, this will depend on the quality of the fabric, based on facts in the fabrication system.
It could be oriented for near perpendicular incidence of the laser beam, or at Brewster's angle. It can be set in some strong mount which also acts as a warmth sink. Greater crystals are frequently employed for side pumping e.g. with higher-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。
