The commonest laser-active exceptional earth ions and host media along with some standard emission wavelengths are demonstrated in the next table:

These ions enable the crystal to amplify light at the laser wavelength via stimulated emission, when energy is equipped into the crystal by using absorption of pump light-weight (�?optical pumping

Laser crystals are optical crystals �?typically one crystals (monocrystalline optical elements) �?which happen to be applied as obtain media for strong-state lasers. Typically, These are doped with either trivalent scarce earth ions or transition metal 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。

This is not difficult to do: just find the lock icon before the URL from the deal with bar and drag that to the bookmark toolbar Together with the mouse. In the event you locate the bookmark entry too very long, you can suitable-click on it to edit the textual content, e.g. making use of "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。

A large surface top quality is needless to say essential. Requirements of floor flatness are often better than . This helps in order to avoid both of those scattering losses and wavefront distortions which could degrade the laser's beam high-quality. Furthermore, scratch and dig requirements

探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。

Several laser crystal components have been shown where some saturable absorber product is integrated for passive Q switching of a laser.

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。

These surfaces which might be passed because of the laser beam are Generally 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。
