The commonest laser-Energetic uncommon earth ions and host media along with some normal emission wavelengths are shown in the following desk:
These ions enable the crystal to amplify light-weight on the laser wavelength via stimulated emission, when Electrical power is provided to 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：
晶体生长 晶体加工 镀膜能�?品质管理 研发能力 新闻中心
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 An additional illustration, Q-switched lasers reach a better inhabitants density in the upper laser degree and so are consequently far more delicate to quenching consequences and energy transfer processes; as a result, a decrease doping density is commonly suitable for these products. For top-ability lasers, lessen doping densities tend to be used to Restrict the density of warmth era, Despite the fact that slim-disk lasers get the job done finest with remarkably doped crystals. Several laser items don't get to the entire functionality prospective for the reason that these types of facts have not been thoroughly worked out.
The host crystal is far more than just a means to repair the laser-Lively ions at certain positions in Area. Many Qualities in the host substance are crucial:
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 distinctive applications result in really unique prerequisites on laser attain media. For this reason, a wide vary of various crystals are employed, and producing the proper choice is important for setting up lasers with ideal functionality.
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。
For Laser Crystal various explanations, composite crystals are getting to be well known. These have a spatially different chemical composition and may be produced with special shapes.
It might be oriented for near perpendicular incidence on the laser beam, or at Brewster's angle. It may be preset in some strong mount which also functions like a warmth sink. More substantial crystals are frequently employed for side pumping e.g. with substantial-energy 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。
