Laser modeling and simulation can be employed to reliably figure out the the best possible crystal dimensions, doping density And maybe values of more parameters.

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 and also the upper-state lifetime.

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 probable doping concentration can rely strongly around the host substance and its fabrication technique.

g. a skinny disk. As another instance, Q-switched lasers arrive at a better inhabitants density within the higher laser level and therefore are thus much more sensitive to quenching consequences and energy transfer processes; as a result, a decrease doping density is often appropriate for these units. For top-power lasers, reduced doping densities in many cases are utilized to limit the density of heat generation, Though slim-disk lasers do the job best with very doped crystals. A lot of laser solutions never get to the full efficiency prospective due to the fact these facts haven't been appropriately labored out.

GWU-Lasertechnik has more than thirty several years of expertise in distributing laser crystals. Select GWU to reap the benefits of our wide awareness As well as in-subject encounter!

A superior injury threshold concerning pulse fluence or peak intensity is usually crucial for top-Vitality amplifiers.

These ions help the crystal to amplify mild for the laser wavelength by way of stimulated emission, when Electricity is supplied on the crystal by using absorption of pump mild (�?optical pumping

Which geometry, dopant and doping focus of the obtain medium are most useful depend on numerous elements. The offered pump resource (type of laser diode or lamp) as well as the envisaged pumping arrangement are very important factors, but the material itself also has some affect. One example is, titanium–sapphire lasers ought to be pumped with higher intensities, for which the form of a transversely cooled rod, operated with reasonably smaller pump and laser beam diameter, is a lot more appropriate than e.

It may be oriented for close to perpendicular incidence in the laser beam, or at Brewster's angle. It may be mounted in a few reliable mount which also functions for a warmth sink. Much larger crystals tend to be useful for facet pumping e.g. with significant-electric power diode bars.

The most typical laser-active scarce earth ions and host media website along with some normal emission wavelengths are proven in the following desk:

A handful of laser crystal components are actually demonstrated wherever some saturable absorber materials is integrated for passive Q switching of the laser.

Certainly, it is extremely fascinating that a specified crystal high quality is developed continually, although distinct laser types might have a different sensitivity to material parameters.

There is certainly a wide array of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline buildings. 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

It is apparent that diverse purposes lead to extremely diverse necessities on laser gain media. Because of this, a broad selection of various crystals are made use of, and making the proper selection is essential for setting up lasers with ideal effectiveness.

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。
