激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
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。
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。
This is a snap to accomplish: just discover the lock icon before the URL inside the deal with bar and drag that to your bookmark toolbar Using the mouse. In case you locate the bookmark entry as well long, you'll be able to suitable-simply click it to edit the textual content, e.g. utilizing "RP Enc" in place of "RP Photonics Encyclopedia".
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
A superior surface top quality is not surprisingly important. Technical specs of area flatness are sometimes much better than . This allows to avoid each scattering losses and wavefront distortions which might degrade the laser's beam top quality. Moreover, scratch and dig 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。
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-stage laser gain media or simply 3-level get media, a single often ought to limit the size to a worth which can be too quick for efficient pump absorption, as reabsorption outcomes would if not spoil the effectiveness. For side pumping, further criteria come into Engage in; Other than economical pump absorption, it is vital to get an acceptable spatial condition of your gain profile.

In 2017, we developed the globe’s largest Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW here laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with exceptionally vast emission spectra drives the event of laser diode pumped ultrafast good-state lasers. With the increase in pulse Vitality, peak electric power, and repetition rate of sound-condition lasers, laser crystals will establish towards bigger dimensions, higher crystal top quality, and controllable crucial functionality.
It might be oriented for around perpendicular incidence of your laser beam, or at Brewster's angle. It may be set in certain stable mount which also acts to be a warmth sink. More substantial crystals are generally utilized for side pumping e.g. with significant-energy diode bars.
