The commonest laser-Lively exceptional earth ions and host media along with some typical emission wavelengths are shown in the subsequent table:
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。
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。

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 etc.) that has a wide range of technical specs. Other than the well-established supplies, revolutionary crystals with exceptional Qualities like Yb:CALGO can open new horizons for demanding laser applications. No matter whether or not person pieces for R & D applications are demanded or Charge-successful figures in tiny, medium or big batches with in-time delivery with the generation line are wanted: GWU’s committed support helps to find the greatest Main parts for the software.
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
g. a thin disk. As One more example, Q-switched lasers achieve an increased population density within the higher laser stage and therefore are thus far more sensitive to quenching effects and energy transfer processes; as a result, a decrease doping density is frequently suitable for these devices. For prime-electricity lasers, lower doping densities in many cases are accustomed to limit the density of heat generation, Though skinny-disk lasers perform greatest with very doped crystals. Several laser items usually do not reach the complete general performance opportunity for the reason that these information have not been effectively worked out.
The host crystal is a great deal more than just a way to fix the laser-Energetic ions at particular positions in Place. Several Attributes on the host material are essential:
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。
Individuals surfaces that are handed with the laser beam are Usually both oriented at Brewster's angle or have an anti-reflection coating.
Distinctive crystalline elements are incredibly different relating to their hardness along with other Attributes, which establish with which techniques And just how effortlessly they may be Reduce and polished with top quality.
The medium ought to have a significant transparency (minimal absorption and scattering) within the wavelength regions of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is determined by the quality of the fabric, based on information of your fabrication system.
Working with our advertising and marketing deal, you are able to Display screen your emblem, even more info further under your products description, and these will been noticed by numerous photonics professionals.
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。
