Right here you are able to post issues and remarks. As far as they get accepted through the creator, they're going to look earlier mentioned this paragraph together with the creator’s solution. The writer will choose acceptance based on specific standards. Essentially, The difficulty has to be of adequately broad interest.
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。
On top of that, some flexibility is lost in experiments if one particular simply cannot Check out absorbers with distinctive thickness or doping focus, one example is, without exchanging the laser crystal by 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：

A large area quality is not surprisingly crucial. Requirements of area flatness are sometimes much better than . This aids in order to avoid both of those scattering losses and wavefront distortions that may degrade the laser's beam excellent. Also, scratch and dig technical specs
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
Laser modeling and simulation can be employed to reliably ascertain the optimum crystal Proportions, doping density and possibly values of extra 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。
For quasi-a few-degree laser acquire media or simply three-amount gain media, just one normally must limit the size to a value which happens to be as well quick for economical pump absorption, as reabsorption consequences would in any other case spoil the general performance. For facet pumping, more issues occur into play; Other than effective pump absorption, it can be crucial to obtain an appropriate spatial form of your acquire profile.
Unique crystalline supplies are incredibly various concerning their hardness along with other Homes, which identify with which methods And just how simply they are often Slash and polished with high quality.
The medium must have a substantial transparency (reduced absorption and scattering) within the wavelength areas of pump and laser radiation, and very good optical homogeneity. To some extent, this is determined by the caliber of the material, based on specifics with the fabrication procedure.
It may be oriented for close to perpendicular incidence of the laser beam, or at Brewster's angle. It might be fixed in some strong mount which also acts to be a warmth sink. More substantial crystals usually website are employed for side pumping e.g. with higher-power diode bars.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
