Laser modeling and simulation may be used to reliably determine the optimum crystal Proportions, 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 crystal is a lot more than simply a method to repair the laser-Lively ions at sure positions in Place. Several properties from the host substance are essential:
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-three-amount laser get media as well as three-level attain media, just one frequently really should Restrict the length to a price and that is much too brief for productive pump absorption, as reabsorption effects would usually spoil the overall performance. For facet pumping, extra concerns occur into Perform; Moreover economical pump absorption, it can be crucial to obtain a suitable spatial condition from the get profile.

GWU-Lasertechnik has more than thirty several years of knowledge in distributing laser crystals. Select GWU to take advantage of our broad awareness As well as in-area working experience!
A significant injury threshold when it comes to pulse fluence or peak intensity is usually critical for top-Strength 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 rely on various elements. The offered pump resource (kind of laser diode or lamp) plus the envisaged pumping arrangement are important aspects, but the fabric alone also has some impact. For instance, titanium–sapphire lasers must be pumped with superior intensities, for which the shape of a transversely cooled rod, operated with fairly modest pump and laser beam diameter, is a lot more correct than e.
It may be oriented for close to perpendicular incidence on the laser beam, or at Brewster's angle. It could be preset in certain solid mount which also acts to be a warmth sink. Larger crystals are usually used for facet pumping e.g. with high-power diode bars.
The commonest laser-Lively exceptional earth ions and host media together with some common emission wavelengths are shown in the subsequent table:
A handful of laser crystal elements happen to be demonstrated where some saturable absorber substance is included for passive Q switching of a laser.
For several factors, composite crystals have become preferred. These Use a spatially varying chemical composition and may be designed with Exclusive styles.
There is a wide array of crystalline media, which can be grouped according to special 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 �?ordinarily solitary crystals (monocrystalline optical materials) �?which are utilised as obtain website media for reliable-condition lasers. Most often, they are doped with either trivalent scarce earth ions or transition 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。
