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。

芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。

This is not difficult to try and do: just locate the lock icon in front of the URL within the tackle bar and drag that into the bookmark toolbar With all the mouse. In case you discover the bookmark entry much too extended, you could appropriate-click it to edit the textual content, e.g. employing "RP Enc" in place of "RP Photonics Encyclopedia".

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

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。

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。

Laser modeling and simulation can be employed to reliably establish the optimum crystal dimensions, doping density And maybe values of further parameters.

量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

For quasi-three-stage laser obtain media or perhaps a few-level attain media, a single frequently really should limit the duration to a value and that is also shorter for productive pump absorption, as reabsorption consequences would in any other case spoil the performance. For side pumping, more concerns arrive into Enjoy; besides productive pump absorption, it can be crucial to obtain a suitable spatial shape from the achieve profile.

Diverse crystalline supplies are really distinct about their hardness and also other Attributes, which decide with which solutions And the way simply they may be Reduce and polished with high quality.

GWU-Lasertechnik has much more than thirty yrs of encounter in distributing laser crystals. Opt for GWU to take pleasure in our wide understanding and in-industry experience!

You can find a wide more info range of crystalline media, which can 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。
