The most typical laser-active rare earth ions and host media together with some typical emission wavelengths are revealed in the following desk:
In this article you could post inquiries and remarks. As far as they get accepted with the writer, they are going to seem above this paragraph along with the writer’s remedy. The writer will decide on acceptance based upon specified criteria. Effectively, The problem must be of sufficiently broad desire.
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。
Additionally, some flexibility is shed in experiments if one can't try out absorbers with various thickness or doping concentration, as an example, without having exchanging the laser crystal itself.
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 thin disk. As One more example, Q-switched lasers achieve the next population density while in the higher laser degree and they are consequently far more delicate to quenching consequences and energy transfer processes; as a result, a decrease doping density is frequently suitable for these products. For prime-electric power lasers, lessen doping densities are often used to Restrict the density of heat technology, Whilst slim-disk lasers do the job best with hugely doped crystals. Lots of laser merchandise will not get to the total overall performance prospective due to the fact this sort of particulars haven't been effectively labored out.
The host crystal is much more click here than just a way to fix the laser-Energetic ions at sure positions in Area. Quite a few Houses of the host materials are important:
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。

Diverse crystalline supplies are really distinct about their hardness along with other Attributes, which decide with which solutions And the way simply they may be Slash and polished with good quality.
