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。

This is not difficult to carry out: just find the lock icon before the URL during the address bar and drag that on the bookmark toolbar While using the mouse. In case you find the bookmark entry way too extensive, you are able to proper-click on it to edit the textual content, e.g. using "RP Enc" as opposed to "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。

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。

The host crystal is way more than just a method to repair the laser-active ions at sure positions in House. A number of Qualities from the host content are very more info important:

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

For quasi-a few-degree laser achieve media or even a few-stage attain media, 1 usually needs to limit the length to a worth which happens to be also small for efficient pump absorption, as reabsorption results would normally spoil the overall performance. For aspect pumping, added factors arrive into Perform; Apart from productive pump absorption, it is vital to get an acceptable spatial condition on the get profile.

The medium should have a large transparency (very low absorption and scattering) in the wavelength regions of pump and laser radiation, and excellent optical homogeneity. To some extent, this will depend on the caliber of the material, based on information on the fabrication course of action.

With that concept, 1 isn't going to need an extra saturable absorber crystal, making sure that 1 may possibly make extra compact Q-switched laser setups with reduce internal parasitic losses. Nonetheless, undesirable Unintended effects may also happen, like obtaining unwelcome valence states of your included ions or Strength transfers.

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。
