The commonest laser-Lively unusual earth ions and host media together with some common emission wavelengths are shown in the next table:
These ions help the crystal to amplify gentle with the laser wavelength by means of stimulated emission, when Strength is provided for the crystal by using absorption of pump gentle (�?optical pumping
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。
Which geometry, dopant and doping focus from the get medium are most advantageous depend upon several variables. The accessible pump supply (type of laser diode or lamp) plus the envisaged pumping arrangement are important variables, but the fabric itself also has some affect. Such as, titanium–sapphire lasers need to be pumped with significant intensities, for which the form of a transversely cooled rod, operated with somewhat compact pump and laser beam diameter, is more ideal than e.
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。
The host crystal is much more than just a method to fix the laser-Lively ions at specific positions in space. Quite a few properties with the host materials are essential:
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。

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 a variety of explanations, composite crystals are read more becoming well-liked. These Have a very spatially various chemical composition and might be designed with Distinctive styles.
It might be oriented for around perpendicular incidence with the laser beam, or at Brewster's angle. It might be preset in some solid mount which also acts like a heat sink. Greater crystals are frequently employed for aspect pumping e.g. with significant-electric power diode bars.
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。
