Unique crystalline supplies are very diverse concerning their hardness and various Qualities, which identify with which strategies And just how easily they are often Slice 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 as well as the upper-state 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。
For quasi-three-level laser attain media or simply 3-degree acquire media, one normally ought to limit the length to a worth that's also brief for effective pump absorption, as reabsorption effects would usually spoil the functionality. For side pumping, supplemental issues come into Enjoy; Apart from economical pump absorption, it is crucial to obtain an appropriate spatial shape on the gain profile.
g. a skinny disk. As An additional illustration, Q-switched lasers attain a better inhabitants density within the higher laser amount and are for that reason more sensitive to quenching outcomes and energy transfer processes; consequently, a reduced doping density is frequently suitable for these gadgets. For prime-electric power lasers, lower doping densities tend to be accustomed to limit the density of warmth technology, although thin-disk lasers perform finest with highly doped crystals. Numerous laser merchandise will not get to the comprehensive overall performance prospective due to the fact these facts haven't been thoroughly labored out.
GWU-Lasertechnik has in excess of 30 a long time of encounter in distributing laser crystals. Choose GWU to reap the benefits of our wide awareness As well as in-area expertise!
A large destruction threshold with regard to pulse fluence or peak intensity is often crucial for top-Vitality 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 consist of only the most typical host crystals; quite a few Some others exist, which might be fewer routinely applied.
Here you can post inquiries and remarks. As far as they get recognized with the author, they will surface earlier mentioned this paragraph together with the creator’s response. The author will decide on acceptance dependant on specified criteria. Effectively, The problem must be of adequately broad fascination.
A number of laser crystal products have been demonstrated where by some saturable absorber material is integrated for passive Q switching of a laser.
For various causes, composite crystals have become well-known. These Have a very spatially various chemical composition and will be made with Distinctive 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, one particular does not need to have an additional saturable absorber crystal, in order that one may well make much more compact Q-switched laser setups with decrease internal parasitic losses. Even so, unwanted Uncomfortable side effects can also come about, which include click here getting unwelcome valence states from the concerned ions or Electricity transfers.
