These tables consist of only the commonest host crystals; quite a few Other people exist, which happen to be much less routinely made use of.

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。

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。

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。

The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and in addition the higher-condition life time.

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。

激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。

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 decide the ideal crystal dimensions, doping density And perhaps values of supplemental parameters.

激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。

For quasi-three-amount laser achieve media and even 3-level achieve media, 1 generally needs to Restrict the duration to a value which happens to be as well limited for economical pump absorption, as reabsorption effects would or else spoil the overall performance. For side pumping, supplemental criteria come into play; besides efficient pump absorption, it is necessary to acquire a suitable spatial shape click here with the attain 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。

The medium ought to have a high transparency (very low absorption and scattering) from the wavelength locations of pump and laser radiation, and superior optical homogeneity. To some extent, this will depend on the quality of the fabric, based on information of the fabrication course of action.

Using our promoting package, you may Exhibit your brand, even more down below your item description, and these will been seen by several photonics pros.

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。
