Various crystalline materials are certainly distinctive about their hardness along with other Homes, which identify with which procedures And the way conveniently they are often Minimize and polished with top quality.
The medium must have a significant transparency (low absorption and scattering) inside the wavelength areas of pump and laser radiation, and excellent optical homogeneity. To some extent, this relies on the standard of the fabric, determined by information with the fabrication approach.
The host crystal is a great deal more than just a way to repair the laser-Lively ions at sure positions in Area. A variety of properties of your host product are very important:
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。
The utmost doable doping focus can rely strongly to the host substance and its fabrication system.
g. a skinny disk. As One more instance, Q-switched lasers attain the next inhabitants density while in the upper laser amount and therefore are consequently a lot more delicate to quenching results and Electrical power transfer processes; hence, a decrease doping density is often appropriate for these devices. For prime-energy lasers, decreased doping densities are frequently utilized to limit the density of heat era, Even though skinny-disk lasers get the job done best with very doped crystals. A lot of laser products and solutions do not reach the total performance potential mainly because this sort of particulars haven't been effectively worked out.
GWU-Lasertechnik has a lot more than 30 many years of encounter in distributing laser crystals. Pick out GWU to take advantage of our huge information As well as in-discipline expertise!
A significant harm threshold regarding pulse fluence or peak depth can be essential for high-Power amplifiers.
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：

These tables comprise only the most common host crystals; numerous Other folks exist, which can be less often made use of.
The commonest laser-active rare earth ions and host media together with some regular emission wavelengths are proven in the subsequent table:
People surfaces that happen to be handed with the laser beam are Generally both oriented at Brewster's angle or have an anti-reflection coating.
For many good reasons, composite crystals are getting to be well-liked. These Have got a spatially various chemical composition and will be created with Exclusive designs.
You can find a variety of crystalline media, which can be grouped in accordance to big atomic constituents and crystalline structures. Some critical 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 features all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) that has a broad range of specifications. Moreover the nicely-proven resources, modern crystals with exceptional Homes like Yb:CALGO can open up new horizons for demanding laser purposes. Despite irrespective of whether unique pieces for R & D needs are required or Expense-efficient quantities in modest, medium or large batches with in-time supply with the creation line are necessary: GWU’s dedicated company helps to find the check here ideal Main parts for the application.
Laser crystals are optical crystals �?generally one crystals (monocrystalline optical elements) �?which can be applied as achieve media for strong-point out lasers. Generally, These are doped with both trivalent unusual earth ions or transition metallic 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。
