These tables contain only the most typical host crystals; a lot of Other people exist, that happen to be considerably less usually applied.

Below you are able to post concerns and remarks. So far as they get approved via the author, they'll look earlier mentioned this paragraph along with the writer’s reply. The author will decide on acceptance based on certain requirements. Primarily, the issue needs to be of adequately 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。

Also, some overall flexibility is shed in experiments if 1 cannot try out absorbers with distinct thickness or doping concentration, by way of example, devoid of 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：

GWU features all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) using a broad number of specs. Apart from the nicely-established materials, ground breaking crystals with remarkable Homes like Yb:CALGO can open up new horizons for demanding laser programs. Regardless of regardless of whether individual items for R & D functions are demanded or Value-efficient figures in tiny, medium or significant batches with in-time shipping and delivery with the manufacturing line are desired: GWU’s dedicated provider really helps to discover the very best core parts for your personal 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。

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。

激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。

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-three-amount laser get media or maybe three-level get media, a single frequently ought to limit the duration to a value which happens to be too brief for productive pump absorption, as reabsorption effects would if not spoil the functionality. For side pumping, more criteria occur into play; In addition to efficient pump absorption, it is vital to acquire a suitable spatial form with the acquire profile.

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。

In 2017, we produced the planet’s largest read more Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with incredibly huge emission spectra drives the development of laser diode pumped ultrafast reliable-point out lasers. With the rise in pulse Power, peak electric power, and repetition rate of reliable-condition lasers, laser crystals will develop in the direction of much larger dimensions, bigger crystal quality, and controllable important efficiency.

It may be oriented for in the vicinity of perpendicular incidence of your laser beam, or at Brewster's angle. It can be fixed in certain good mount which also functions like a heat sink. Bigger crystals are often used for facet pumping e.g. with substantial-electricity 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。
