These tables contain only the most typical host crystals; lots of Other folks exist, which can be fewer routinely made use of.

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 focus of your gain medium are most advantageous rely on several components. The obtainable pump supply (kind of laser diode or lamp) and also the envisaged pumping arrangement are essential components, but the material alone also has some influence. One example is, titanium–sapphire lasers should be pumped with higher intensities, for which the form of a transversely cooled rod, operated with somewhat little pump and laser beam diameter, is a lot more ideal than e.

Naturally, it is very appealing that a given crystal top quality is created constantly, Even though distinct laser layouts can have another sensitivity to material parameters.
g. a skinny disk. As another instance, Q-switched lasers achieve an increased inhabitants density within the higher laser amount and they are therefore more sensitive to quenching effects and Power transfer processes; consequently, a reduced doping density is usually appropriate for these gadgets. For high-power lasers, lower doping densities tend to be used to Restrict the density of warmth era, Though thin-disk lasers do the job finest with very doped crystals. Numerous laser products will not reach the full general performance probable simply because such aspects haven't been correctly Laser Crystal labored out.
激光晶体的效率在很大程度上依赖于某些属性,这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。

For quasi-three-level laser obtain media or maybe a few-amount gain media, a single often must limit the length to a value which can be also limited for successful pump absorption, as reabsorption outcomes would usually spoil the general performance. For facet pumping, supplemental considerations occur into Participate in; Other than economical pump absorption, it can be crucial to obtain a suitable spatial condition of your get profile.
Unique crystalline components are very diverse about their hardness along with other Attributes, which ascertain with which methods and how very easily they may be Slash and polished with good quality.
GWU-Lasertechnik has more than 30 several years of expertise in distributing laser crystals. Decide on GWU to gain from our large know-how As well as in-area knowledge!
It may be oriented for in close proximity to perpendicular incidence with the laser beam, or at Brewster's angle. It might be mounted in some good mount which also acts like a warmth sink. Bigger crystals usually are employed for side pumping e.g. with superior-electrical power diode bars.
