These ions empower the crystal to amplify gentle in the laser wavelength through stimulated emission, when Strength is supplied to the crystal by using absorption of pump mild (�?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。
On top of that, some overall flexibility is misplaced in experiments if one simply cannot try out absorbers with distinctive thickness or doping concentration, by way of example, devoid of exchanging the laser crystal by itself.
Which geometry, dopant and doping focus of your obtain medium are most beneficial depend upon numerous variables. The out there pump resource (form of laser diode or lamp) and the envisaged pumping arrangement are crucial variables, but the fabric itself also has some influence. For instance, titanium–sapphire lasers ought to be pumped with superior intensities, for which click here the shape of a transversely cooled rod, operated with rather modest 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。
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 attainable doping focus can count strongly to the host product and its fabrication system.
A couple of laser crystal resources happen to be demonstrated the place some saturable absorber materials is incorporated for passive Q switching of the laser.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

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。
For a variety of explanations, composite crystals are getting to be well-liked. These Have got a spatially different chemical composition and will be built with special designs.
You can find an array of crystalline media, which may be grouped according to special atomic constituents and crystalline buildings. Some essential teams of crystals are:
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。
