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 complete: just find the lock icon before the URL during the deal with bar and drag that on the bookmark toolbar While using the mouse. Just in case you discover the bookmark entry way too lengthy, you can suitable-click it to edit the textual content, e.g. using "RP Enc" in lieu 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 significant surface excellent is not surprisingly essential. Technical specs of area flatness are often better than . This aids in order to avoid equally scattering losses and wavefront distortions which might degrade the laser's beam good quality. Moreover, scratch and dig requirements
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。
The host crystal is a great deal more than just a way to fix the laser-Energetic ions at selected positions in space. Numerous Homes on the host substance are essential:
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 obvious that unique apps produce pretty distinctive requirements on laser get media. This is why, a broad range of various crystals are utilised, and creating the right preference is essential for developing lasers with ideal efficiency.

For several good reasons, composite crystals have become popular. These Use a spatially varying chemical composition and will be created with special designs.
It could be oriented for in close proximity to perpendicular incidence with the laser beam, or at Brewster's angle. It could be mounted in a few strong mount which also read more functions for a heat sink. Greater crystals are often used for facet pumping e.g. with large-energy 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。
