The most common laser-Lively uncommon earth ions and host media together with some regular emission wavelengths are revealed in the following table:
These ions empower the crystal to amplify gentle with the laser wavelength through stimulated emission, when Strength is provided towards the crystal via absorption of pump light-weight (�?optical pumping
Laser crystals are optical crystals �?usually single crystals (monocrystalline optical materials) �?which happen to be made use of as get media for reliable-point out lasers. In most cases, They may be doped with either trivalent scarce earth ions or transition metal ions.
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
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：
GWU offers all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) by using a wide selection of requirements. Moreover the effectively-proven components, modern crystals with remarkable Attributes like Yb:CALGO can open new horizons for demanding laser applications. Despite no matter if person items for R & D needs are demanded or Expense-economical figures in compact, medium or significant batches with in-time supply for that manufacturing line are essential: GWU’s website focused support helps you to find the ideal Main components for the software.
A substantial surface area good quality is needless to say important. Requirements of area flatness are often a lot better than . This helps to stop both equally scattering losses and wavefront distortions that may degrade the laser's beam high quality. Moreover, scratch and dig specs
The utmost achievable doping focus can depend strongly to the host material and its fabrication strategy.
A few laser crystal elements have been shown in which some saturable absorber material is included for passive Q switching of a laser.
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 clear that distinctive purposes result in extremely different requirements on laser attain media. This is why, a broad variety of various crystals are utilised, and creating the ideal alternative is essential for constructing lasers with the best possible effectiveness.
