The commonest laser-Energetic uncommon earth ions and host media along with some normal 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。
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。
Additionally, some adaptability is misplaced in experiments if just one simply cannot try out absorbers with diverse thickness or doping focus, one example is, with no exchanging the laser crystal alone.
Which geometry, dopant and doping focus of the obtain medium are most useful depend on many components. The accessible pump source (kind of laser diode or lamp) plus the envisaged pumping arrangement are crucial aspects, but the material itself also has some impact. One example is, titanium–sapphire lasers should be pumped with significant intensities, for which the form of a transversely cooled rod, operated with relatively small pump and laser beam diameter, is a lot more ideal than e.

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 One more example, Q-switched lasers get to a greater populace density within the higher laser level and so are as a result extra sensitive to quenching effects and energy transfer processes; therefore, a decrease doping density is usually suitable for these devices. For prime-energy lasers, decreased doping densities tend to be accustomed to limit the density of heat technology, Even though slim-disk lasers perform greatest with remarkably doped crystals. Quite a few laser goods do not get to the whole efficiency probable due to the fact these particulars haven't been effectively labored out.
The host crystal is a great deal more than simply a means to repair the laser-Lively ions at selected positions in Room. Quite a few Homes of the host material are very important:
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。
These surfaces which might be handed with the laser beam are Commonly both oriented at Brewster's angle or website have an anti-reflection coating.
Distinct crystalline elements are really various concerning their hardness and also other Qualities, which identify with which methods and how very easily they are often Slice and polished with high quality.
