These ions allow the crystal to amplify mild at the laser wavelength by way of stimulated emission, when Electrical power is provided for the crystal by means of absorption of pump light-weight (�?optical pumping
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
Also, some flexibility is lost in experiments if one cannot Check out absorbers with different thickness or doping concentration, for example, devoid of exchanging the laser crystal itself.
Which geometry, dopant and doping concentration on the get medium are most useful depend upon quite a few factors. The out there pump source (style of laser diode or lamp) as well as the envisaged pumping arrangement are important aspects, but the material itself also has some influence. One example is, titanium–sapphire lasers must be pumped with high intensities, for which the form of the transversely cooled rod, operated with comparatively small pump and laser beam diameter, is more suitable 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。
A superior area high-quality is of course important. Technical specs of floor flatness in many cases are much better than . This aids in order to avoid the two scattering losses and wavefront distortions which might degrade the laser's beam high quality. In addition, scratch and dig requirements
The most feasible doping concentration can rely strongly to the host product and its fabrication technique.
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。
People surfaces which happen to be handed by the laser beam are normally possibly oriented at Brewster's angle or have an anti-reflection coating.
Distinct crystalline elements are quite distinctive regarding their hardness together with other Qualities, which identify with which strategies And the way conveniently they can be Slice get more info and polished with high quality.
For a variety of causes, composite crystals are getting to be common. These Have a very spatially different chemical composition and can be produced with Unique shapes.
It might be oriented for in the vicinity of perpendicular incidence of your laser beam, or at Brewster's angle. It might be preset in a few reliable mount which also functions as being a warmth sink. Larger crystals are usually useful for aspect pumping e.g. with large-ability 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。
