Laser modeling and simulation can be employed to reliably determine the the best possible crystal dimensions, doping density And maybe values of added 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 in addition the higher-condition life time.

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-level laser gain media or simply a few-degree acquire media, 1 frequently ought to limit the size to a worth which can be too limited for effective pump absorption, as reabsorption effects would or else spoil the overall performance. For side pumping, extra concerns occur into Engage in; Apart from economical pump absorption, it's important to get a suitable spatial form on the get profile.

GWU-Lasertechnik has a lot more than thirty yrs of working experience in distributing laser crystals. Select GWU to gain from our large understanding and in-discipline knowledge!

A high damage threshold in terms of pulse fluence or peak depth might be vital for prime-energy amplifiers.

作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：

Which geometry, dopant and doping focus of the achieve medium are most useful depend upon quite a few things. The offered pump resource (kind of laser diode or lamp) as well as envisaged pumping arrangement are very important things, but the fabric alone also has some impact. For instance, titanium–sapphire lasers must be pumped with superior intensities, for which the shape of website a transversely cooled rod, operated with reasonably compact pump and laser beam diameter, is a lot more appropriate than e.

It may be oriented for around perpendicular incidence with the laser beam, or at Brewster's angle. It could be preset in certain good mount which also functions to be a warmth sink. Larger crystals are usually used for side pumping e.g. with high-power diode bars.

The most typical laser-Energetic uncommon earth ions and host media together with some usual emission wavelengths are demonstrated in the next table:

All those surfaces which can be handed with the laser beam are normally both oriented at Brewster's angle or have an anti-reflection coating.

Not surprisingly, it is very appealing that a presented crystal quality is created persistently, although various laser patterns can have a distinct sensitivity to materials parameters.

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

Laser crystals are optical crystals �?commonly single crystals (monocrystalline optical components) �?which happen to be utilized as achieve media for good-state lasers. Usually, They are really doped with possibly trivalent uncommon earth ions or changeover metallic 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。
