The commonest laser-Lively unusual earth ions and host media along with some typical emission wavelengths are proven in the next table:
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
Laser crystals are optical crystals �?generally one crystals (monocrystalline optical supplies) �?which can be applied as get media for stable-state lasers. Generally, These are doped with both trivalent scarce earth ions or changeover 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 in the get medium are most beneficial depend on many components. The available pump source (variety of laser diode or lamp) and also the envisaged pumping arrangement are crucial components, but the fabric itself also has some affect. For example, titanium–sapphire lasers must be pumped with superior intensities, for which the form of the transversely cooled rod, operated with reasonably little pump and laser beam diameter, is much more ideal than e.
GWU gives all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) having a wide a number of technical specs. Besides the well-established supplies, revolutionary crystals with excellent Qualities like Yb:CALGO can open new horizons for demanding laser purposes. No matter whether or not person parts for R & D applications are demanded or Charge-effective numbers in small, medium or significant batches with in-time shipping to the production line are needed: GWU’s focused provider helps to locate the finest core factors for your personal software.
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。
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。

Individuals surfaces that happen to be passed via the laser beam are Generally either 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。
The medium should have a higher transparency (minimal absorption and scattering) while in the wavelength areas of pump and laser radiation, and fantastic optical homogeneity. To some click here extent, this relies on the standard of the fabric, based on facts with the fabrication course of action.
It might be oriented for in close proximity to perpendicular incidence of the laser beam, or at Brewster's angle. It may be mounted in a few stable mount which also functions as a heat sink. Greater crystals are frequently useful for facet pumping e.g. with high-energy diode bars.
