激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。

Furthermore, some versatility is dropped in experiments if one particular are unable to Check out absorbers with diverse thickness or doping focus, for example, without exchanging the laser crystal alone.

The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and likewise the higher-point out lifetime.

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。

Needless to say, it is rather desirable that a given crystal quality is manufactured continually, Despite the fact that unique laser types can have another sensitivity to content parameters.

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。

The host crystal is a lot more than simply a method to repair the laser-active ions at specific positions in Place. Many Qualities get more info on the host content are very important:

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。

For quasi-3-level laser get media or even 3-stage attain media, 1 typically needs to limit the length to a price and that is also small for productive pump absorption, as reabsorption outcomes would or else spoil the effectiveness. For aspect pumping, added concerns appear into Enjoy; besides economical pump absorption, it is crucial to acquire an acceptable spatial condition with the achieve profile.

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。

For many reasons, composite crystals are becoming popular. These have a spatially different chemical composition and will be designed with Distinctive shapes.

Employing our promotion offer, you'll be able to Show your brand, further beneath your solution description, and these will been observed by a lot of photonics specialists.

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。
