The most typical laser-active unusual earth ions and host media together with some typical emission wavelengths are revealed 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 �?ordinarily solitary crystals (monocrystalline optical products) �?which might be utilized as gain media for reliable-state lasers. Typically, They're doped with either trivalent unusual earth ions or changeover metallic ions.
In addition, some versatility is dropped in experiments if one particular cannot try out absorbers with distinct thickness or doping concentration, by way of example, without having exchanging the laser crystal by itself.
This is not hard to perform: just find the lock icon in front of the URL within the tackle bar and drag that for the bookmark toolbar Using the mouse. In the event you locate the bookmark entry also extensive, you'll be able to suitable-click it to edit the text, e.g. employing "RP Enc" instead of "RP Photonics Encyclopedia".
GWU features all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) by using a wide a number of technical specs. Other than the perfectly-founded elements, ground breaking crystals with remarkable Homes like Yb:CALGO can open new horizons for demanding laser purposes. It does not matter no matter whether personal pieces for R & D needs are required or cost-economical figures in little, medium or significant batches with in-time shipping for the creation line are needed: GWU’s devoted company helps to discover the finest Main components on your software.
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
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 establish the optimum crystal Proportions, doping density and possibly values of more parameters.
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
For quasi-3-amount laser get media or even a few-amount achieve media, a person often really should limit the length to a worth which is much too small for economical pump absorption, as reabsorption outcomes would if not spoil the general performance. For side pumping, extra factors appear into Enjoy; Other than productive pump absorption, it is important to acquire an acceptable spatial condition of your gain profile.
Distinct crystalline supplies are really distinctive relating to their hardness as well as other Houses, which figure out with which procedures and how simply they may be Reduce and polished with high quality.
GWU-Lasertechnik has much more than thirty years of expertise in distributing laser crystals. Opt for GWU to take pleasure in our broad information and in-subject working experience!
There exists a wide array Laser Crystal of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline structures. Some essential groups of crystals are:
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。
