The commonest laser-Energetic exceptional earth ions and host media together with some standard emission wavelengths are revealed in the following desk:
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
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。
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：
GWU gives all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) with a broad variety of technical specs. Moreover the well-recognized components, progressive crystals with superb Houses like Yb:CALGO can open new horizons for demanding laser purposes. Despite regardless of whether unique items for R & D functions are required or Charge-economical figures in compact, medium or large batches with in-time shipping for that manufacturing line are needed: GWU’s focused assistance helps you to find the best core elements for your personal application.
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 A different case in point, Q-switched lasers reach a greater population density while in the upper laser stage and so are as a result far more sensitive to quenching results and Strength transfer procedures; thus, a lessen doping density is commonly suitable for these equipment. For top-power lasers, lower doping densities are frequently used to limit the density of warmth era, Despite the fact that slim-disk lasers operate ideal with hugely doped crystals. A lot of laser merchandise usually do not reach the full performance opportunity simply because these specifics have not been thoroughly worked out.
Laser modeling and simulation can be utilized to reliably determine the the best possible crystal dimensions, doping density And maybe values of added 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。
Those surfaces which happen to be passed by the laser beam are Commonly either oriented at Brewster's angle or have an anti-reflection coating.
Unique crystalline components are very diverse concerning their hardness together with other Qualities, which identify with which strategies And just how very easily they can be Reduce and polished with good quality.
GWU-Lasertechnik has over thirty decades of working experience in distributing laser crystals. Select GWU to benefit from our vast know-how As well as in-field expertise!
It could be oriented read more for near perpendicular incidence from the laser beam, or at Brewster's angle. It could be fixed in some reliable mount which also functions for a warmth sink. Larger crystals are often utilized for aspect pumping e.g. with substantial-power 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。
