The most typical laser-Lively rare earth ions and host media along with some typical emission wavelengths are demonstrated in the next table:
These ions enable the crystal to amplify light at the laser wavelength by means of stimulated emission, when Electrical power is supplied to the crystal via absorption of pump gentle (�?optical pumping
Laser crystals are optical crystals �?commonly single crystals (monocrystalline optical materials) �?which might be applied as attain media for sound-state lasers. Normally, These are doped with either trivalent exceptional earth ions or transition steel ions.
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。
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
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 substantial area excellent is certainly critical. Requirements of area flatness are sometimes much better than . This aids to prevent equally scattering losses and wavefront distortions which may degrade the laser's beam high-quality. Additionally, scratch and more info 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。
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
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 apparent that diverse programs bring about really distinctive demands on laser achieve media. Because of this, a broad range of various crystals are employed, and generating the ideal decision is important for developing lasers with ideal effectiveness.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
GWU-Lasertechnik has a lot more than thirty a long time of working experience in distributing laser crystals. Decide on GWU to take advantage of our broad understanding and in-discipline encounter!
Applying our promotion bundle, you are able to display your brand, more beneath your products description, and these will been witnessed by numerous photonics gurus.
