Different crystalline resources are extremely unique concerning their hardness and various Homes, which identify with which techniques 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 life span.
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 most achievable doping focus can depend strongly over the host substance and its fabrication process.

GWU-Lasertechnik has in excess of 30 many years of encounter in distributing laser crystals. Decide on GWU to take pleasure in our huge information and in-industry knowledge!
A large harm threshold with regards to pulse fluence or peak depth could be vital for prime-Electrical 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：
Which geometry, dopant and doping concentration of your obtain medium are most beneficial count on numerous components. The available pump supply (style of laser diode or lamp) and the envisaged pumping arrangement are essential variables, but the fabric alone also has some influence. As an example, titanium–sapphire lasers must be pumped with significant intensities, for which the shape of the transversely cooled rod, operated with relatively tiny pump and laser beam diameter, is much more acceptable than e.
It could be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It can be fixed in some strong mount which also acts like a heat sink. Greater crystals are frequently employed for aspect pumping e.g. with significant-ability diode bars.
The commonest laser-Lively unusual read more earth ions and host media together with some common emission wavelengths are revealed in the subsequent table:
Several laser crystal products are already shown in which some saturable absorber product is integrated for passive Q switching of the laser.
For numerous good reasons, composite crystals have become popular. These Possess a spatially various chemical composition and might be built with Distinctive shapes.
There may be a variety of crystalline media, that may be grouped in accordance to important atomic constituents and crystalline structures. Some essential groups of crystals are:
With That idea, a person does not need an additional saturable absorber crystal, to ensure that a single could make far more compact Q-switched laser setups with decrease inside parasitic losses. Even so, undesirable Uncomfortable side effects may arise, for example acquiring undesirable valence states in the involved ions or energy transfers.
GWU gives all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) which has a wide selection of specifications. Other than the properly-set up materials, impressive crystals with fantastic Qualities like Yb:CALGO can open up new horizons for demanding laser apps. Despite whether or not person pieces for R & D applications are demanded or Value-effective figures in little, medium or substantial batches with in-time delivery for that production line are wanted: GWU’s dedicated provider helps to discover the most effective core parts for your application.
Laser crystals are optical crystals �?typically solitary crystals (monocrystalline optical products) �?which can be applied as gain media for reliable-point out lasers. Generally, They can be doped with possibly trivalent rare earth ions or transition steel 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。
