The most typical laser-active uncommon earth ions and host media together with some standard emission wavelengths are proven in the following desk:

These ions allow the crystal to amplify light within the laser wavelength by way of stimulated emission, when energy is equipped for the crystal via absorption of pump gentle (�?optical pumping

为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。

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。

Which geometry, dopant and doping focus on the get medium are most beneficial count on several variables. The obtainable pump resource (type of laser diode or lamp) along with the envisaged pumping arrangement are important things, but the fabric by itself also has some influence. By way of example, titanium–sapphire lasers have to be pumped with large intensities, for which the form of the transversely cooled rod, operated with relatively modest pump and laser beam diameter, is much more correct than e.

Obviously, it is extremely appealing that a offered crystal top quality is made regularly, Even though distinct laser patterns can have another sensitivity to substance parameters.

亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。

Laser modeling and simulation can be used to reliably identify the ideal crystal Proportions, doping density and possibly values of additional parameters.

激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。

For quasi-3-degree laser acquire media or even 3-level attain media, one particular usually needs to limit the duration to a value which is way too quick for efficient pump absorption, as reabsorption results would if not spoil the functionality. For facet pumping, more factors come into Engage in; Other than effective pump absorption, it is crucial to acquire a suitable spatial shape in the achieve profile.

Unique crystalline components are very unique concerning their hardness and various Qualities, which figure out with which procedures and how simply they may be Minimize and polished with top quality.

GWU-Lasertechnik has much more than thirty years of expertise in distributing laser crystals. Decide on GWU to take pleasure in our large knowledge As well as in-industry experience!

There exists a wide array of crystalline more info media, which may be grouped in accordance to big atomic constituents and crystalline structures. Some vital groups of crystals are:

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。
