5 Simple Techniques For Laser Crystal

These tables consist of only the most common host crystals; several Many others exist, that are less usually made use of.

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 single crystals (monocrystalline optical materials) �?that are utilised as achieve media for strong-point out lasers. Most often, They may be doped with either trivalent scarce earth ions or transition steel ions.

Furthermore, some adaptability is lost in experiments if a single are not able to try out absorbers with distinct thickness or doping concentration, for instance, with out exchanging the laser crystal alone.

作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：

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。

Of course, it is very desirable that a given crystal high quality is created regularly, Even though different laser layouts might have a distinct sensitivity to materials parameters.

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。

Several laser crystal materials are already shown exactly where some saturable absorber substance is included 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。

Those surfaces which are handed from the laser beam are normally both oriented at Brewster's angle or have an anti-reflection coating.

The medium ought to have a substantial transparency (minimal absorption and scattering) in the wavelength locations of pump and laser radiation, and good optical homogeneity. To some extent, this is determined by the standard of the material, determined by specifics with the fabrication process.

With That idea, one particular would not have to have an additional saturable absorber crystal, to make sure that a single may more info make more compact Q-switched laser setups with reduced internal parasitic losses. However, unwelcome side effects might also happen, for instance acquiring unwanted valence states of your included ions or Strength transfers.

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。
