Laser crystals are optical crystals �?usually solitary crystals (monocrystalline optical products) �?that happen to be utilised as gain media for reliable-point out lasers. Most often, They may be doped with possibly trivalent rare earth ions or transition metallic ions.
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 not hard to perform: just find the lock icon in front of the URL while in the address bar and drag that on the bookmark toolbar Using the mouse. In the event you locate the bookmark entry also extensive, you'll be able to suitable-simply click it to edit the text, e.g. using "RP Enc" in place of "RP Photonics Encyclopedia".
GWU delivers all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) having a broad selection of specs. In addition to the nicely-established materials, innovative crystals with superb Houses like Yb:CALGO can open new horizons for demanding laser applications. Regardless of regardless of whether person parts for R & D reasons are required or Expense-efficient figures in small, medium or massive batches with in-time delivery to the production line are essential: GWU’s focused support helps to discover the best core parts for your personal application.
Certainly, it is very desirable that a given crystal quality is produced consistently, although distinctive laser layouts may have a special sensitivity to material parameters.
The utmost probable doping concentration can count strongly about read more the host content and its fabrication method.
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 obtain media or perhaps 3-stage get media, one particular often ought to limit the size to a price which happens to be way too short for productive pump absorption, as reabsorption consequences would in any other case spoil the general performance. For side pumping, further issues occur into Participate in; In addition to effective pump absorption, it is necessary to obtain an appropriate spatial form on the achieve profile.

The medium ought to have a substantial transparency (very low absorption and scattering) inside the wavelength locations of pump and laser radiation, and very good optical homogeneity. To some extent, this depends upon the standard of the material, determined by details on the fabrication process.
Utilizing our advertising and marketing package, it is possible to display your emblem, even more down below your item description, and these will been witnessed by lots of photonics experts.
