These tables include only the commonest host crystals; numerous Many others exist, which can be a lot less commonly made use of.
These ions empower the crystal to amplify mild at the laser wavelength by using stimulated emission, when Electricity is equipped on the crystal by way of absorption of pump light-weight (�?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（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。
This is simple to carry out: just locate the lock icon before the URL inside the handle bar and drag that towards the bookmark toolbar Along with the mouse. In case you find the bookmark entry way too extensive, you are able to appropriate-click on it to edit the textual content, e.g. applying "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 higher floor quality is naturally vital. Specifications of surface flatness are frequently a lot better than . This will help to stay away from both scattering losses and wavefront distortions which may degrade the laser's beam high quality. Furthermore, scratch and dig specs
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
Several laser crystal components are demonstrated exactly where some saturable absorber product is incorporated for passive Q switching of the laser.

For quasi-three-stage laser obtain media as well as 3-stage get media, one particular frequently really should limit the size to a value and that is as well small for effective pump absorption, as reabsorption outcomes would or else spoil the overall performance. For aspect pumping, additional issues occur into Perform; Aside from economical pump absorption, it's important to acquire an acceptable spatial shape from the obtain profile.
Various crystalline products are quite various relating to their hardness and also other properties, which establish with which methods And the way effortlessly they are often Slash and polished with good quality.
The medium must have a large transparency (low absorption and scattering) during the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this will depend on the quality of the fabric, determined by details of the fabrication course of action.
It could be oriented for in the vicinity of perpendicular incidence of your laser beam, or at Brewster's angle. It can be fixed in some check here solid mount which also functions being a heat sink. More substantial crystals are frequently employed for side pumping e.g. with higher-energy 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。
