These tables comprise only the most common host crystals; quite a few Other individuals exist, which are considerably less commonly used.
These ions permit the crystal to amplify light for the laser wavelength by means of stimulated emission, when Vitality is supplied to your crystal by way of absorption of pump light-weight (�?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（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。
Which geometry, dopant and doping concentration in the gain medium are most advantageous depend on several factors. The available pump resource (style of laser diode or lamp) plus the envisaged pumping arrangement are very important aspects, but the material by itself also has some impact. For instance, titanium–sapphire lasers should be pumped with large intensities, for which the form of a transversely cooled rod, operated with fairly little pump and laser beam diameter, is a lot more ideal than e.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
Naturally, it is extremely desirable that a supplied crystal top quality is produced regularly, Whilst unique laser patterns can have a unique sensitivity to materials 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。
A few laser crystal elements have already been shown where some saturable absorber content is incorporated for passive Q switching of the laser.
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-a few-degree laser gain media or simply 3-amount achieve media, a single often must Restrict the size to a value that is much too quick for economical pump absorption, as reabsorption results would if not spoil the efficiency. For facet pumping, additional issues occur into Perform; Aside from economical pump absorption, it is vital to get an appropriate spatial form of your gain profile.

For many explanations, composite crystals Laser Crystal are getting to be well known. These Have a very spatially varying chemical composition and will be designed with Specific shapes.
It might be oriented for close to perpendicular incidence in the laser beam, or at Brewster's angle. It may be mounted in a few good mount which also functions being a warmth sink. More substantial crystals usually are useful for aspect pumping e.g. with superior-electrical power diode bars.
