These ions help the crystal to amplify mild for the laser wavelength by means of stimulated emission, when Power is equipped on the crystal through absorption of pump light (�?optical pumping
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
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：
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
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。
g. a thin disk. As Yet another example, Q-switched lasers achieve a greater inhabitants density from the higher laser stage and so are thus additional sensitive to quenching effects and Strength transfer procedures; hence, a lessen doping density is usually appropriate for these devices. For top-power lasers, lower doping densities will often be utilized to Restrict the density of heat generation, Though slender-disk lasers work ideal with really doped crystals. Several laser merchandise don't reach the comprehensive efficiency prospective for the reason that this sort of details have not been thoroughly labored out.
Laser modeling and simulation can be employed to reliably figure out the optimum crystal dimensions, doping density And maybe 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 distinctive applications cause incredibly different demands on laser get media. For this reason, a broad variety of different crystals are employed, and producing the ideal choice is important for developing lasers with ideal general performance.
Diverse crystalline components are extremely different relating to their hardness and also other website properties, which ascertain with which strategies And exactly how simply they may be Slice and polished with good quality.
The medium ought to have a higher transparency (very low absorption and scattering) within the wavelength regions of pump and laser radiation, and fantastic optical homogeneity. To some extent, this will depend on the caliber of the fabric, determined by information in the fabrication process.
Utilizing our advertising and marketing package, you can Show your logo, more under your solution description, and these will been witnessed by many photonics industry experts.
