The 5-Second Trick For Nonlinear Crystal

Blog Article

Laser modeling and simulation can be employed to reliably figure out the optimum crystal dimensions, doping density and possibly values of further 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 upper-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。

The utmost probable doping concentration can rely strongly on the host materials and its fabrication method.

GWU-Lasertechnik has a lot more than thirty yrs of encounter in distributing laser crystals. Pick out GWU to get pleasure from our huge know-how and in-discipline encounter!

A superior injury threshold in terms of pulse fluence or peak intensity is usually important for top-Power 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 concentration of your obtain medium are most useful depend on many things. The obtainable pump supply (variety of laser diode or lamp) as well as the envisaged pumping arrangement are crucial factors, but the material by itself also has some affect. Such as, titanium–sapphire lasers have to be pumped with substantial intensities, for which the shape of the transversely cooled rod, operated with relatively tiny pump and laser beam diameter, is much more ideal than e.

It could be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It may be mounted in a few stable mount which also functions to be a warmth sink. Larger crystals are often utilized for side pumping e.g. with large-power diode bars.

The most common laser-Lively exceptional earth ions and host media along with some standard emission wavelengths are proven in the following desk:

Individuals surfaces which are handed by the laser beam are Commonly either oriented at Brewster's angle or have an anti-reflection coating.

Of course, it is extremely fascinating that a specified crystal high quality is developed continuously, although distinct laser models might have a different 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 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

Laser crystals are optical crystals �?typically solitary crystals (monocrystalline optical products) �?which can be made use of as acquire media for stable-state lasers. Normally, They are really Laser Crystal doped with either trivalent unusual 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。
