These tables include only the most typical host crystals; lots of others exist, which can be a lot less frequently employed.
Below you can submit queries and responses. So far as they get approved via the creator, they will seem over this paragraph together with the author’s reply. The writer will make a decision on acceptance based upon specific requirements. In essence, The problem need to be of adequately broad curiosity.
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
Also, some versatility is shed in experiments if one particular can not Check out absorbers with distinct thickness or doping focus, by way of example, with out 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：
GWU offers all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) using a broad number of specifications. In addition to the nicely-set up supplies, progressive crystals with excellent properties like Yb:CALGO can open up new horizons for demanding laser purposes. It does not matter irrespective of whether unique items for R & D needs are needed or Price-economical figures in tiny, medium or big batches with in-time delivery for that creation line are required: GWU’s focused provider helps to locate the ideal core parts 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。
The most probable doping concentration can rely strongly to the host material and its fabrication strategy.
Laser modeling and simulation may be used to reliably identify the the best possible crystal dimensions, doping density And perhaps values of further 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。
It is apparent that distinct apps result in incredibly different requirements on laser acquire media. This is why, a broad variety of different crystals are utilised, and building the best option is essential for constructing lasers with the best possible functionality.

The medium must have a significant transparency (low absorption and scattering) in the wavelength regions of pump and laser radiation, and great optical homogeneity. To some extent, this is get more info dependent upon the caliber of the fabric, determined by information on the fabrication course of action.
It might be oriented for in the vicinity of perpendicular incidence from the laser beam, or at Brewster's angle. It may be fastened in certain solid mount which also acts like a heat sink. Much larger crystals tend to be used for side pumping e.g. with large-electricity 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。
