The most common laser-Lively exceptional earth ions and host media along with some common emission wavelengths are revealed in the next 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 �?commonly single crystals (monocrystalline optical elements) �?that are utilised as achieve media for reliable-point out lasers. Normally, These are doped with either trivalent rare earth ions or changeover metallic 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 focus of the get medium are most useful count on several variables. The readily available pump source (style of laser diode or lamp) along with the envisaged pumping arrangement are crucial factors, but the material itself also has some impact. By way of example, titanium–sapphire lasers must be pumped with higher intensities, for which the shape of a transversely cooled rod, operated with fairly compact pump and laser beam diameter, is much more appropriate 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。

活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。

g. a thin disk. As A further instance, Q-switched lasers access read more a higher populace density during the upper laser degree and so are therefore a lot more sensitive to quenching outcomes and Electrical power transfer processes; consequently, a decrease doping density is frequently appropriate for these gadgets. For prime-electricity lasers, decreased doping densities will often be used to Restrict the density of warmth technology, While slim-disk lasers get the job done finest with remarkably doped crystals. Quite a few laser solutions will not reach the complete overall performance prospective simply because such aspects haven't been properly labored out.

The host crystal is a lot more than simply a method to fix the laser-active ions at specified positions in space. Several Houses of your host materials are essential:

热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

Those surfaces which are handed through the laser beam are normally both oriented at Brewster's angle or have an anti-reflection coating.

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。

GWU-Lasertechnik has much more than thirty years of expertise in distributing laser crystals. Pick GWU to get pleasure from our huge understanding As well as in-subject knowledge!

There is 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:

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。
