These tables contain only the most typical host crystals; lots of Other individuals exist, which are significantly less commonly utilised.
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。
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
Moreover, some adaptability is lost in experiments if a single are unable to Check out absorbers with distinctive thickness or doping focus, for instance, without having exchanging the laser crystal by itself.
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：
晶体生长 晶体加工 镀膜能�?品质管理 研发能力 新闻中心
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。
The utmost probable doping focus can rely strongly around the host material and its fabrication process.
The host crystal is a lot more than simply a way to repair the laser-Energetic ions at particular positions in Place. Several properties on the host materials are crucial:
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。
For quasi-a few-stage laser get media or even a few-amount achieve media, just one usually needs to Restrict the length to a value that is also quick for effective pump absorption, as reabsorption results would otherwise spoil the performance. For aspect pumping, supplemental issues come into play; Other than economical pump absorption, it can be crucial to get an appropriate spatial condition from the gain profile.

The medium should have a high transparency (lower absorption and scattering) within the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this is determined by the standard of the fabric, based on information with the fabrication procedure.
With that concept, a single will not want an extra saturable absorber crystal, making sure that just one may possibly make far more compact Q-switched laser setups with reduce interior parasitic losses. Nonetheless, unwelcome Uncomfortable side effects may arise, for instance obtaining undesirable get more info valence states of your concerned ions or energy transfers.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
