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

激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。

Laser crystals are optical crystals �?usually solitary crystals (monocrystalline optical supplies) �?which happen to be employed as acquire media for stable-condition lasers. In most cases, they are doped with both trivalent exceptional earth ions or changeover metal ions.

激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。

Which geometry, dopant and doping concentration of your gain medium are most useful count on various components. The readily available pump supply (sort of laser diode or lamp) as well as the envisaged pumping arrangement are important things, but the material itself also has some affect. Such as, titanium–sapphire lasers should be pumped with high intensities, for which the shape of a transversely cooled rod, operated with rather modest pump and laser beam diameter, is more ideal than e.

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。

Naturally, it is rather appealing that a specified crystal high-quality is generated persistently, Though distinctive laser models 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。

A couple of laser crystal products are demonstrated where by some saturable absorber content is included for passive Q switching of a laser.

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-a few-degree laser gain media or simply 3-level get media, one particular frequently really should limit the size to a value and that is as well quick for economical pump absorption, as reabsorption results would if not spoil the functionality. For facet pumping, extra things to consider come into Engage in; Other than effective pump absorption, it is necessary to acquire an acceptable spatial condition of the acquire profile.

In 2017, we produced the whole world’s premier Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with really large emission spectra drives the event of laser diode pumped ultrafast solid-state lasers. With the increase in pulse Vitality, peak electric power, and repetition price of sound-condition lasers, laser crystals will acquire to bigger sizes, larger crystal good quality, and controllable critical general performance.

There may be a wide range of crystalline media, which can be grouped according to important atomic constituents and crystalline constructions. Some critical teams of crystals are:

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。
