These tables contain only the most typical host crystals; a lot of others exist, that are considerably less often utilized.
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。

The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and also the higher-point out lifetime.
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。
g. a skinny disk. As An additional illustration, Q-switched lasers reach a better inhabitants density within the upper laser stage and they are for that reason more sensitive to quenching results and Strength transfer procedures; therefore, a reduced doping density is frequently suitable for these products. For prime-ability lasers, lower doping densities tend to be used to Restrict the density of warmth technology, While slim-disk lasers perform ideal with hugely doped crystals. Several laser items usually do not reach the full performance opportunity mainly because these kinds of particulars haven't been effectively labored out.
The host crystal check here is a great deal more than simply a means to fix the laser-Energetic ions at selected positions in space. Several Homes of your host material are important:
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。
It is obvious that unique purposes produce very different specifications on laser acquire media. Because of this, a broad range of various crystals are applied, and generating the correct selection is essential for developing lasers with ideal efficiency.
材料 激光晶体 晶体生长 光学性能 稀土离子 过渡族离子 products laser crystal crystal growth optical functionality exceptional earth ions changeover team ions
The medium must have a substantial transparency (small absorption and scattering) from the wavelength areas of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends on the standard of the fabric, determined by facts of your fabrication process.
With That idea, one won't need to have an extra saturable absorber crystal, to make sure that one particular may possibly make a lot more compact Q-switched laser setups with reduced internal parasitic losses. Having said that, unwanted Unwanted side effects could also come about, including getting undesirable valence states of the included 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。
