The commonest laser-Lively unusual earth ions and host media along with some normal emission wavelengths are shown 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。

This is not difficult to complete: just locate the lock icon in front of the URL while in the address bar and drag that on the bookmark toolbar Together with the mouse. Just in case you discover the bookmark entry too extended, you could right-click it to edit the text, e.g. making use of "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 large floor quality is needless to say critical. Technical specs of area flatness are sometimes better than . This aids in order to avoid equally scattering losses and wavefront distortions which often can degrade the laser's beam high-quality. On top of that, scratch and dig technical 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。
Laser modeling and simulation can be employed to reliably identify the ideal crystal dimensions, doping density and possibly values of further parameters.
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-3-stage laser obtain media or perhaps a few-stage gain media, a single often must Restrict the length to a value and that is also small for productive pump absorption, as reabsorption consequences would normally spoil the general performance. For aspect pumping, additional factors occur into Engage in; Moreover economical pump absorption, it is crucial to get an acceptable spatial shape of your achieve profile.

The medium must have a higher transparency (low absorption and scattering) from the wavelength regions of pump and laser radiation, and superior optical homogeneity. To some extent, this will depend on the quality of the fabric, based on specifics of the fabrication approach.
With That idea, one does not need yet another saturable absorber crystal, to make sure that a person may perhaps make much more compact Q-switched laser setups with reduce interior parasitic losses. Having said that, undesired Uncomfortable side effects here may additionally happen, which include getting undesirable valence states of the included ions or Power transfers.
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。
