The most typical laser-active unusual earth ions and host media together with some normal emission wavelengths are demonstrated in the next table:
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。
Laser crystals are optical crystals �?typically solitary crystals (monocrystalline optical products) �?which might be utilized as gain media for good-state lasers. Most often, They can be doped with possibly trivalent unusual earth ions or changeover metal ions.
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
This is simple to perform: just locate the lock icon in front of the URL while in the handle bar and drag that towards the bookmark toolbar Together with the mouse. Just in case you locate the bookmark entry much too long, you are able to proper-click it to edit the text, e.g. using "RP Enc" rather than "RP Photonics Encyclopedia".
GWU provides all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) which has a wide selection of specifications. Aside from the effectively-set up supplies, innovative crystals with superb Homes like Yb:CALGO can open up new horizons for demanding laser apps. Irrespective of regardless of whether individual items for R & D reasons are demanded or Value-economical numbers in smaller, medium or large batches with in-time shipping and delivery with the production line are necessary: GWU’s committed company helps to discover the finest Main factors for your application.
活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。
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 utilized to reliably identify the ideal crystal Proportions, doping density and possibly values of further parameters.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
For quasi-3-level laser attain media as well as three-stage acquire media, a person frequently should Restrict the length to a price which is way too shorter for effective pump absorption, as reabsorption outcomes would if not spoil the efficiency. For aspect pumping, supplemental concerns occur into play; Apart from productive pump absorption, it can be crucial to acquire an acceptable spatial condition of your attain profile.
Distinct crystalline materials are certainly distinct about their hardness and also other Attributes, which establish with which solutions And the way quickly they can be Lower and polished with high quality.
For various reasons, composite crystals are getting to more info be common. These Have a very spatially different chemical composition and can be manufactured with Distinctive styles.
It might be oriented for in close proximity to perpendicular incidence of your laser beam, or at Brewster's angle. It might be preset in certain good mount which also functions to be a warmth sink. Much larger crystals usually are employed for aspect pumping e.g. with large-electrical 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。
