The commonest laser-active exceptional earth ions and host media together with some common emission wavelengths are demonstrated in the next desk:
These ions enable the crystal to amplify light in the laser wavelength via stimulated emission, when Power is supplied to the crystal via 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。

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 offers all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) using a wide variety of technical specs. Besides the nicely-established resources, ground breaking crystals with exceptional properties like Yb:CALGO can open up new horizons for demanding laser apps. Irrespective of whether or not unique items for R & D uses are required or cost-effective numbers in modest, medium or huge batches with in-time supply for your production line are wanted: GWU’s devoted provider helps to discover the ideal Main components to your software.
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
g. a skinny disk. As One more case in point, Q-switched lasers get to the next population density during the upper laser stage and are as a result more delicate to quenching results and energy transfer procedures; for that reason, a lessen doping density is usually suitable for these gadgets. For prime-power lasers, lessen doping densities are frequently utilized to limit the density of heat era, Even though website thin-disk lasers function finest with remarkably doped crystals. Several laser solutions will not reach the full effectiveness prospective since such particulars have not been properly labored out.
Laser modeling and simulation may be used to reliably decide the the best possible crystal Proportions, doping density And perhaps values of further parameters.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
It is clear that unique apps bring about really distinct prerequisites on laser attain media. This is why, a broad range of various crystals are utilised, and producing the proper preference is essential for constructing lasers with the best possible overall performance.

GWU-Lasertechnik has in excess of thirty many years of practical experience in distributing laser crystals. Select GWU to benefit from our extensive awareness and in-discipline practical experience!
There may be a wide range of crystalline media, which can be grouped in accordance to big atomic constituents and crystalline structures. Some crucial teams of crystals are:
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。
