The most common laser-Lively rare earth ions and host media along with some regular emission wavelengths are demonstrated in the following desk:
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 �?usually solitary crystals (monocrystalline optical components) �?which are utilised as acquire media for stable-state lasers. Usually, they are doped with either trivalent unusual earth ions or changeover metallic ions.
Furthermore, some adaptability is dropped in experiments if one particular are not able to Check out absorbers with diverse thickness or doping concentration, one example is, without the need of 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：
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。
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 most attainable doping focus can count strongly about the host material and its fabrication strategy.
The host crystal is a great deal more than just a method to repair the laser-Energetic ions at specified positions in House. Several Houses of the host materials are very important:
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
It is obvious that diverse apps bring on very different specifications on laser obtain media. For that reason, a broad variety of different crystals are used, and making the right alternative is important for setting up lasers with ideal general performance.
Distinctive crystalline materials are quite various relating to their hardness along with other properties, which establish with which methods And the way conveniently they can be Lower and polished with top quality.
GWU-Lasertechnik has much more than 30 years of working experience in distributing laser crystals. Opt for GWU to take advantage of our extensive expertise and in-discipline knowledge!
With That idea, just one would not have to have yet another saturable absorber crystal, to make sure that a person may perhaps make additional compact Q-switched laser setups with decreased inner parasitic losses. Nonetheless, unwanted Negative effects may also manifest, for instance obtaining read more unwelcome valence states in the involved ions or Electricity 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。
