Distinctive crystalline resources are incredibly distinctive regarding their hardness along with other Attributes, which decide with which solutions And the way quickly they can be Minimize and polished with top quality.
The medium should have a significant transparency (small absorption and scattering) inside the wavelength areas of pump and laser radiation, and superior optical homogeneity. To some extent, this depends upon the caliber of the fabric, based on aspects of the fabrication method.
The host crystal is much more than just a method to repair the laser-active ions at particular positions in Room. A variety of Attributes of the host material are 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。
For quasi-3-amount laser gain media and even a few-amount acquire media, one particular typically needs to Restrict the length to a worth and that is much too shorter for economical pump absorption, as reabsorption consequences would if not spoil the general performance. For facet pumping, supplemental considerations occur into play; Apart from effective pump absorption, it is vital to get a suitable spatial shape in the gain profile.
g. a thin disk. As An additional instance, Q-switched lasers access a better population density in the higher laser stage and so are for that reason a lot more sensitive to quenching consequences and energy transfer processes; hence, a decreased doping density is usually suitable for these equipment. For prime-power lasers, decrease doping densities will often be utilized to Restrict the density of heat generation, although slender-disk lasers get the job done finest with highly doped crystals. Numerous laser products will not reach the whole efficiency probable mainly because such specifics have not been appropriately labored out.
GWU-Lasertechnik has greater than thirty yrs of knowledge in distributing laser crystals. Select GWU to reap the benefits of our extensive expertise As well as in-discipline working experience!
A superior damage threshold in terms of pulse fluence or peak intensity may be critical 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：

It may be oriented for close to perpendicular incidence with the laser beam, or at Brewster's angle. It could be set in certain stable mount which also functions being a heat sink. Larger sized crystals are frequently used for facet pumping e.g. with substantial-power diode bars.
In this article you could post queries and responses. In terms of they get accepted through the writer, they'll website surface previously mentioned this paragraph along with the creator’s solution. The writer will settle on acceptance depending on selected criteria. Primarily, the issue have to be of adequately wide interest.
Several laser crystal supplies are demonstrated where some saturable absorber materials is incorporated for passive Q switching of a laser.
For numerous reasons, composite crystals have become well-liked. These Possess a spatially different chemical composition and can be made 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。

GWU gives all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) using a wide number of specs. Apart from the nicely-established materials, innovative crystals with outstanding properties like Yb:CALGO can open new horizons for demanding laser programs. Irrespective of no matter if specific pieces for R & D applications are essential or Expense-efficient figures in modest, medium or big batches with in-time supply for your output line are necessary: GWU’s focused services really helps to find the ideal core elements on your software.
Laser crystals are optical crystals �?usually solitary crystals (monocrystalline optical supplies) �?which happen to be utilised as attain media for sound-condition lasers. Most often, They may be doped with both trivalent exceptional earth ions or changeover metal ions.
