These tables include only the most typical host crystals; several Some others exist, which are significantly less regularly employed.
These ions help the crystal to amplify mild within the laser wavelength through stimulated emission, when Electrical power is provided into the crystal by way of 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（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 easy to try and do: just find the lock icon in front of the URL from the address bar and drag that for the bookmark toolbar with the mouse. In case you discover the bookmark entry far too long, you'll be able to suitable-simply click it to edit the text, e.g. using "RP Enc" in place of "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 high-quality is obviously critical. Requirements of area flatness are often better than . This aids in order to avoid both equally scattering losses and wavefront distortions which often can degrade the laser's beam quality. Additionally, scratch and dig technical 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。
A number of laser crystal supplies are already demonstrated the Laser Crystal place some saturable absorber product is included for passive Q switching of the laser.
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。
For quasi-three-stage laser get media or simply a few-amount achieve media, one usually has to limit the duration to a value that is also limited for effective pump absorption, as reabsorption results would normally spoil the effectiveness. For side pumping, further factors arrive into Enjoy; Aside from successful pump absorption, it is vital to acquire an acceptable spatial form with the obtain profile.
Diverse crystalline products are certainly distinctive about their hardness and other Qualities, which identify with which techniques And just how easily they are often Reduce and polished with high quality.
For various explanations, composite crystals have gotten well-liked. These Possess a spatially different chemical composition and will be made with Unique styles.
It may be oriented for close to perpendicular incidence on the laser beam, or at Brewster's angle. It might be preset in certain good mount which also functions for a warmth sink. Much larger crystals tend to be useful for aspect pumping e.g. with substantial-electricity diode bars.
