The most common laser-Lively unusual earth ions and host media together with some regular emission wavelengths are proven in the subsequent table:

These ions allow the crystal to amplify gentle for the laser wavelength through stimulated emission, when Electricity is provided to your crystal through absorption of pump light-weight (�?optical pumping

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 skinny disk. As Yet another illustration, Q-switched lasers reach a better inhabitants density in the upper laser stage and are as a result additional delicate to quenching consequences and Power transfer processes; as a result, a reduce doping density is usually suitable for these products. For top-power lasers, reduce doping densities are frequently accustomed to limit the density of heat generation, While thin-disk lasers perform very best with hugely doped crystals. Numerous laser goods will not get to the entire functionality opportunity since this kind of aspects have not been correctly labored out.

The host crystal is way more info more than just a method to repair the laser-active ions at specified positions in House. Numerous Houses of your host materials 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 clear that distinctive apps result in incredibly distinctive requirements on laser gain media. Because of this, a broad range of various crystals are made use of, and earning the ideal selection is essential for setting up lasers with the best possible functionality.

Various crystalline products are very distinct regarding their hardness and also other Homes, which ascertain with which strategies and how conveniently they are often Minimize and polished with high quality.

For different explanations, composite crystals have gotten well-liked. These have a spatially various chemical composition and might be made with Specific styles.

There is certainly a wide array of crystalline media, which may be grouped in accordance to big atomic constituents and crystalline structures. Some essential groups of crystals are:

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。
