The commonest laser-Energetic uncommon earth ions and host media together with some common emission wavelengths are revealed in the subsequent table:
These ions help the crystal to amplify gentle at the laser wavelength by means of stimulated emission, when Power is equipped for the crystal via absorption of pump gentle (�?optical pumping
Laser crystals are optical crystals �?typically solitary crystals (monocrystalline optical materials) �?which happen to be employed as attain media for stable-state lasers. Normally, they are doped with either trivalent rare earth ions or transition steel ions.
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 from the acquire medium are most beneficial depend upon numerous aspects. The obtainable pump source (type of laser diode or lamp) and the envisaged pumping arrangement are crucial components, but the fabric alone also has some affect. For instance, titanium–sapphire lasers have to be pumped with superior intensities, for which the click here form of the transversely cooled rod, operated with rather modest 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。
The utmost feasible doping focus can depend strongly around the host product and its fabrication approach.
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。
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。
