These tables consist of only the commonest host crystals; many Many others exist, which are a lot less often made use of.
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 �?usually solitary crystals (monocrystalline optical elements) �?which are applied as gain media for solid-state lasers. In most cases, These are doped with possibly trivalent scarce earth ions or changeover metal 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 simple to do: just locate the lock icon in front of the URL during the handle bar and drag that into the bookmark toolbar Along with the mouse. In the event you find the bookmark entry much too prolonged, you are able to right-click on it to edit the text, e.g. working with "RP Enc" as opposed to "RP Photonics Encyclopedia".
GWU delivers all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) by using a wide variety of specifications. Apart from the properly-founded products, innovative crystals with excellent Homes like Yb:CALGO can open up new horizons for demanding laser purposes. Irrespective of no matter if particular person items for R & D reasons are essential or Value-efficient quantities in tiny, medium or huge batches with in-time delivery with the generation line are essential: GWU’s devoted assistance helps you to find the most effective more info core components in your application.
Certainly, it is very desirable that a provided crystal high-quality is produced regularly, Even though various laser styles can have another sensitivity to product parameters.
The utmost feasible doping focus can rely strongly around the host material and its fabrication strategy.
Laser modeling and simulation may be used to reliably establish the optimum crystal Proportions, doping density And maybe values of more 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。
It is obvious that distinctive programs bring about incredibly different needs on laser achieve media. Due to this, a wide selection of various crystals are made use of, and making the proper selection is essential for constructing lasers with optimum overall performance.

In 2017, we made the entire world’s biggest Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with really huge emission spectra drives the event of laser diode pumped ultrafast solid-state lasers. With the increase in pulse Electricity, peak electrical power, and repetition level of strong-point out lasers, laser crystals will produce toward bigger sizes, bigger crystal top quality, and controllable crucial functionality.
There exists a variety of crystalline media, which can be grouped in accordance to important atomic constituents and crystalline constructions. Some significant groups of crystals are:
