Various crystalline products are very distinctive regarding their hardness and various Qualities, which ascertain with which approaches And just how simply they may be Slash and polished with high quality.
The medium must have a large transparency (very low absorption and scattering) from the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this is determined by the standard of the fabric, based on details of your fabrication method.
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions as well as the higher-condition lifetime.
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 maximum attainable doping focus can depend strongly around the host material and its fabrication technique.

GWU-Lasertechnik has a lot more than thirty a long time of practical experience in distributing laser crystals. Choose GWU to get pleasure from our huge know-how and in-field experience!
A large destruction threshold regarding pulse fluence or peak depth might be important for prime-energy 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：
Which geometry, dopant and doping concentration with the acquire medium are most beneficial rely upon several variables. The out there pump source (form of laser diode or lamp) as well as envisaged pumping arrangement are important aspects, but the fabric read more alone also has some impact. For example, titanium–sapphire lasers need to be pumped with substantial intensities, for which the shape of the transversely cooled rod, operated with rather small pump and laser beam diameter, is more proper than e.
It might be oriented for in close proximity to perpendicular incidence of your laser beam, or at Brewster's angle. It might be fixed in some solid mount which also acts being a warmth sink. Much larger crystals tend to be useful for facet pumping e.g. with superior-ability diode bars.
The most typical laser-Energetic uncommon earth ions and host media along with some usual emission wavelengths are demonstrated in the next table:
A couple of laser crystal elements happen to be shown where some saturable absorber content is included for passive Q switching of a laser.
For a variety of reasons, composite crystals have become common. These Have got a spatially varying chemical composition and might be built with Unique designs.
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。
With That idea, just one would not have to have yet another saturable absorber crystal, so that one may make more compact Q-switched laser setups with lower internal parasitic losses. However, unwelcome side effects may also manifest, which include getting undesirable valence states in the involved ions or energy transfers.
GWU gives all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) that has a broad variety of technical specs. Aside from the effectively-established products, modern crystals with excellent Attributes like Yb:CALGO can open new horizons for demanding laser applications. It does not matter no matter whether person parts for R & D functions are demanded or Expense-economical figures in compact, medium or massive batches with in-time delivery to the output line are necessary: GWU’s focused services helps you to locate the greatest Main components to your software.
It is obvious that diverse purposes lead to extremely diverse necessities on laser attain media. For this reason, a broad assortment of different crystals are utilised, and building the ideal choice is important for constructing lasers with optimum overall performance.
