Distinctive crystalline resources are quite different regarding their hardness as well as other Houses, which determine with which approaches And exactly how effortlessly they are often Slash and polished with good quality.
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。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and in addition the upper-condition life time.
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。
For quasi-a few-degree laser obtain media or perhaps three-amount get media, one particular usually must Restrict the size to a price which is far too limited for productive pump absorption, as reabsorption results would otherwise spoil the general performance. For aspect pumping, additional criteria arrive into play; Moreover effective pump absorption, it is important to get an acceptable spatial form of your obtain profile.
g. a thin disk. As One more case in point, Q-switched lasers achieve an increased population density while in the higher laser level and so are hence much more delicate to quenching consequences and Power transfer processes; thus, a lower doping density is usually suitable for these products. For top-energy lasers, reduced doping densities in many cases are accustomed to limit the density of heat generation, Despite the fact that slender-disk lasers work greatest with remarkably doped crystals. Lots of laser products don't reach the total effectiveness opportunity because this kind of particulars have not been effectively worked out.
GWU-Lasertechnik has over 30 several years of working experience in distributing laser crystals. Select GWU to take advantage of our huge understanding As well as in-subject encounter!
On top of that, some versatility is shed in experiments if 1 are unable to Check out absorbers with different thickness or doping concentration, for instance, with out exchanging the laser crystal by itself.
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
Which geometry, dopant and doping concentration with the get medium are most advantageous rely on quite a few variables. The obtainable pump resource (form of laser diode or lamp) and also the envisaged pumping arrangement are crucial factors, but the material alone also has some influence. As an example, titanium–sapphire lasers have to be pumped with significant intensities, for which the form of the transversely cooled rod, operated with reasonably little pump and laser beam diameter, is a lot more ideal than e.
These tables consist of only the most typical host crystals; many others exist, that are a lot less routinely made use of.
The most typical laser-Energetic uncommon earth ions and host media along with some regular emission wavelengths are demonstrated in the next desk:
A couple of laser crystal resources have already been demonstrated the place some saturable absorber material is integrated for passive Q switching of a laser.
For many factors, composite crystals are becoming common. These have a spatially various chemical composition and may be designed with Particular designs.
There's a wide array of crystalline media, that may be grouped according to big atomic constituents and crystalline constructions. Some significant groups of crystals are:
蓝宝�?柱面�?球罩 偏振�?棱镜 红外光学元件 反射�?光学窗口 非球面镜 波片 分光�?制造能力
GWU provides all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) using a broad number of specifications. Besides the well-founded components, revolutionary crystals with exceptional Homes like Yb:CALGO can open up new horizons for demanding laser purposes. No matter regardless of whether specific pieces for R & D needs are needed or Expense-effective quantities in smaller, medium or big batches with in-time delivery for the manufacturing line are desired: GWU’s devoted company helps you to discover the greatest core parts for the application.
It is clear that website diverse programs result in extremely different prerequisites on laser get media. For that reason, a broad variety of various crystals are applied, and creating the ideal selection is important for developing lasers with optimum effectiveness.
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。
