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 �?normally solitary crystals (monocrystalline optical resources) �?which happen to be made use of as attain media for sound-condition lasers. Generally, They're doped with possibly trivalent exceptional earth ions or transition steel ions.
In addition, some adaptability is lost in experiments if 1 simply cannot Check out absorbers with diverse thickness or doping concentration, as an example, without having exchanging the laser crystal itself.
Which geometry, dopant and doping concentration of the attain medium are most useful depend upon a number of things. The readily available pump supply (type of laser diode or lamp) as well as envisaged pumping arrangement are very important factors, but the fabric alone 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 fairly smaller pump and laser beam diameter, is more acceptable than e.

A higher surface high quality is needless to say critical. Requirements of floor flatness will often be better than . This helps to avoid both scattering losses and wavefront distortions that may degrade the laser's beam high-quality. Also, scratch and dig specs
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
A couple of laser crystal elements more info happen to be shown where by some saturable absorber materials is incorporated for passive Q switching of a 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。
It is obvious that diverse apps bring on pretty distinctive requirements on laser gain media. For this reason, a wide vary of various crystals are utilised, and building the right alternative is important for constructing lasers with the best possible effectiveness.

For several good reasons, composite crystals have become well-known. These have a spatially different chemical composition and might be produced with special styles.
It may be oriented for close to perpendicular incidence on the laser beam, or at Brewster's angle. It could be fastened in a few reliable mount which also acts like a heat sink. Larger crystals are usually used for facet pumping e.g. with significant-electrical power diode bars.
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。
