Various crystalline elements are extremely various concerning their hardness along with other Qualities, which identify with which strategies And the way conveniently they may be 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 crystal is a lot more than simply a way to repair the laser-Lively ions at specified positions in Place. A variety of Homes from the host product are essential:
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-stage laser achieve media as well as three-amount gain media, a single normally ought to Restrict the length to a worth that is also small for efficient pump absorption, as reabsorption consequences would in any other case spoil the effectiveness. For facet pumping, added issues come into Enjoy; Apart from economical pump absorption, it is necessary to acquire a suitable spatial form from the gain profile.
g. a thin disk. As A further instance, Q-switched lasers attain a better populace density during the higher laser amount and therefore are hence far more delicate to quenching effects and Strength transfer processes; therefore, a reduce doping density is frequently appropriate for these products. For top-energy lasers, decreased doping densities are often accustomed to limit the density of warmth generation, Despite the fact that skinny-disk lasers operate finest with very doped crystals. A lot of laser merchandise never get to the whole general performance possible since these kinds of information have not been adequately labored out.
GWU-Lasertechnik has a lot more than 30 decades of working experience in distributing laser crystals. Pick GWU to get pleasure from our huge awareness As well as in-area working experience!
On top of that, some flexibility is shed in experiments if one particular can not try out absorbers with different thickness or doping focus, as an example, with no exchanging the laser crystal itself.
These ions enable the crystal to amplify light for the laser wavelength through stimulated emission, when Electrical power is provided to the crystal by using absorption of pump light (�?optical pumping

These tables have only the most common host crystals; a lot of Many others exist, that happen to be considerably less frequently utilized.
The most common laser-active exceptional earth ions and host media along with some standard emission wavelengths are shown in the following desk:
A number read more of laser crystal elements have been demonstrated exactly where some saturable absorber product is integrated for passive Q switching of a laser.
Certainly, it is rather desirable that a given crystal quality is made continually, although different laser designs can have a distinct sensitivity to substance parameters.
There is a variety of crystalline media, which may be grouped in accordance to big atomic constituents and crystalline structures. Some important groups of crystals are:
蓝宝�?柱面�?球罩 偏振�?棱镜 红外光学元件 反射�?光学窗口 非球面镜 波片 分光�?制造能力
GWU provides all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) with a wide number of specs. In addition to the very well-set up supplies, innovative crystals with superb Attributes like Yb:CALGO can open up new horizons for demanding laser purposes. Regardless of no matter whether personal parts for R & D purposes are demanded or Price-successful quantities in small, medium or big batches with in-time supply for that generation line are necessary: GWU’s devoted support really helps to find the greatest core parts for your personal software.
Laser crystals are optical crystals �?ordinarily solitary crystals (monocrystalline optical supplies) �?that happen to be applied as achieve media for sound-point out lasers. Typically, They can be doped with either trivalent scarce earth ions or changeover metal 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。
