Laser modeling and simulation can be used to reliably ascertain the optimum crystal Proportions, doping density and possibly values of further parameters.
The medium should have a significant transparency (lower absorption and scattering) while in the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this depends upon the standard of the material, based on facts from the fabrication approach.
The host crystal is much more than simply a method to fix the laser-Energetic ions at certain positions in Room. Many Homes of your host content are crucial:
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 depend strongly about the host product and its fabrication technique.
g. a skinny disk. As Yet another illustration, Q-switched lasers arrive at a greater population density while in the higher laser amount and so are thus much more delicate to quenching effects and energy transfer procedures; for that reason, a reduced doping density is commonly suitable for these units. For top-electrical power lasers, decreased doping densities are sometimes accustomed to Restrict the density of heat technology, While thin-disk lasers perform best with extremely doped crystals. Several laser solutions don't get to the entire overall performance probable mainly because this kind of specifics have not been effectively worked out.
GWU-Lasertechnik has in excess of 30 many years of encounter in distributing laser crystals. Opt for GWU to benefit from our extensive know-how and in-area expertise!
A large destruction threshold regarding pulse fluence or peak depth may be significant for high-Electricity 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 focus on the acquire medium are most advantageous depend upon several variables. The available pump source (form of laser diode or lamp) along with the envisaged pumping arrangement are crucial aspects, but the material itself also has some affect. One example is, titanium–sapphire lasers should be pumped with superior intensities, for which the shape of the transversely cooled rod, operated with rather small pump and laser beam diameter, is more suitable than e.
It might be oriented for near perpendicular incidence with the laser beam, or at Brewster's angle. It might be fastened in a few strong mount which also functions like a heat sink. Larger sized crystals are often useful for facet pumping e.g. with superior-ability diode bars.
The commonest laser-active rare earth ions and host media together with some usual emission wavelengths are revealed in the following desk:
A couple of laser crystal materials have been demonstrated in which some saturable absorber material is integrated for passive Q switching of a laser.
For several motives, composite crystals are becoming well known. These Possess a spatially different chemical composition and can be produced with special shapes.
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 won't will need a further saturable absorber crystal, making sure that just one may well make far more compact Q-switched laser setups with reduced inner parasitic losses. Nevertheless, unwelcome Unwanted side effects may also come about, including more info getting undesired valence states in the involved ions or Electricity transfers.
GWU offers all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) that has a wide assortment of technical specs. Aside from the effectively-established resources, innovative crystals with fantastic Houses like Yb:CALGO can open new horizons for demanding laser programs. It does not matter regardless of whether personal items for R & D applications are required or Price-productive figures in smaller, medium or significant batches with in-time supply with the output line are desired: GWU’s dedicated service really helps to locate the finest Main parts to your application.
Laser crystals are optical crystals �?normally single crystals (monocrystalline optical products) �?which might be utilised as attain media for reliable-state lasers. Most often, They can be doped with either trivalent exceptional earth ions or transition steel ions.
