The commonest laser-Energetic scarce earth ions and host media together with some usual emission wavelengths are demonstrated in the next desk:
These ions permit the crystal to amplify gentle in the laser wavelength by using stimulated emission, when Strength is supplied towards the crystal by way of absorption of pump mild (�?optical pumping
Laser crystals are optical crystals �?usually one crystals (monocrystalline optical materials) �?which are employed as attain media for strong-point out lasers. In most cases, they are doped with possibly trivalent exceptional earth ions or transition metal ions.
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
Which geometry, dopant and doping focus of your get medium are most useful rely upon various things. The out there pump resource (style of laser diode or lamp) plus the envisaged pumping arrangement are very important variables, but the fabric itself also has some influence. Such as, titanium–sapphire lasers ought to be pumped with superior intensities, for which the form of the transversely cooled rod, operated with relatively small pump and laser beam diameter, is much more correct than e.
GWU offers all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) which has a broad selection of technical specs. Aside from the very well-set up products, ground breaking crystals with outstanding Homes like Yb:CALGO can open up new horizons for demanding laser apps. It does not matter whether person pieces for R & D purposes are demanded or Value-productive figures in small, medium or large batches with in-time supply more info with the production line are required: GWU’s devoted support helps to find the best Main parts in 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。
g. a skinny disk. As Yet another illustration, Q-switched lasers access an increased population density from the upper laser amount and are hence much more sensitive to quenching consequences and energy transfer procedures; as a result, a reduce doping density is often appropriate for these units. For top-electric power lasers, lower doping densities are frequently used to limit the density of warmth technology, Despite the fact that slim-disk lasers work very best with hugely doped crystals. A lot of laser solutions never get to the total functionality probable for the reason that these types of aspects haven't been thoroughly labored out.
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。
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。
Those surfaces which can be passed via the laser beam are Commonly possibly oriented at Brewster's angle or have an anti-reflection coating.
Unique crystalline resources are extremely different concerning their hardness and other Attributes, which identify with which solutions And just how very easily they can be Slash and polished with high quality.
The medium should have a superior transparency (minimal absorption and scattering) during the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this depends upon the quality of the material, based on particulars of the fabrication process.
Applying our promoting package deal, you can Exhibit your brand, further under your product description, and these will been witnessed by numerous photonics industry experts.
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。
