Unique crystalline supplies are extremely unique concerning their hardness and other Homes, which identify with which strategies And just how easily they are often Slice and polished with top 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 considerably more than simply a method to repair the laser-Lively ions at certain positions in Area. Quite a few Houses with the host product 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 maximum doable doping concentration can rely strongly on the host content and its fabrication method.
g. a skinny disk. As another instance, Q-switched lasers arrive at a greater populace density in the upper laser stage and they are consequently additional delicate to quenching consequences and Electrical power transfer procedures; hence, a decrease doping density is usually appropriate for these devices. For high-electrical power lasers, reduce doping densities are sometimes used to Restrict the density of heat era, although skinny-disk lasers do the job greatest with highly doped crystals. A lot of laser solutions don't get to the whole efficiency opportunity for the reason that this kind of information have not been effectively labored out.
GWU-Lasertechnik has in excess of thirty years of expertise in distributing laser crystals. Opt for GWU to benefit from our extensive awareness and in-industry encounter!
A significant hurt threshold concerning pulse fluence or peak depth is often important for high-Electrical power amplifiers.
These ions enable the crystal to amplify light within the laser wavelength by means of stimulated emission, when Strength is equipped to your crystal via absorption of pump mild (�?optical pumping
Which geometry, dopant and doping focus of the attain medium are most useful rely on several components. The obtainable pump resource (style of laser diode or lamp) as well as envisaged pumping arrangement are very important variables, but the material alone also has some influence. As an example, titanium–sapphire lasers must be pumped with significant intensities, for which the form of a transversely cooled rod, operated with comparatively compact pump and laser beam diameter, is more suitable than e.
It may be oriented for near perpendicular incidence of your laser beam, or at Brewster's angle. It might be fastened in certain good mount which also functions click here like a warmth sink. Larger sized crystals tend to be employed for side pumping e.g. with superior-electrical power diode bars.
The most typical laser-Lively unusual earth ions and host media along with some usual emission wavelengths are proven in the next desk:
A couple of laser crystal materials have already been demonstrated the place some saturable absorber material is incorporated for passive Q switching of the laser.
For many causes, composite crystals have become preferred. These Use a spatially various chemical composition and can be created 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 features all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) that has a broad variety of specifications. In addition to the properly-established elements, ground breaking crystals with superb Attributes like Yb:CALGO can open up new horizons for demanding laser apps. It doesn't matter whether particular person pieces for R & D applications are essential or Price-efficient figures in tiny, medium or huge batches with in-time supply for your generation line are desired: GWU’s focused support really helps to locate the greatest Main parts in your application.
Laser crystals are optical crystals �?ordinarily single crystals (monocrystalline optical supplies) �?which might be applied as attain media for stable-condition lasers. Usually, They may be doped with either trivalent scarce earth ions or changeover steel ions.
