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。
Laser crystals are optical crystals �?ordinarily single crystals (monocrystalline optical products) �?that happen to be made use of as achieve media for good-state lasers. Typically, They are really doped with possibly trivalent uncommon earth ions or transition steel ions.
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
This is not difficult to do: just find the lock icon in front of the URL from the address bar and drag that for the bookmark toolbar Along with the mouse. Just in case you locate the bookmark entry too extended, it is possible to suitable-click on it to edit the textual content, e.g. using "RP Enc" rather than "RP Photonics Encyclopedia".
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 another case in point, Q-switched lasers achieve the next population density within the higher laser amount and are thus more sensitive to quenching results and Electricity transfer procedures; therefore, a reduced doping density is frequently suitable for these products. For top-ability lasers, lower doping densities are sometimes accustomed to limit the more info density of heat era, Despite the fact that skinny-disk lasers operate ideal with hugely doped crystals. A lot of laser merchandise tend not to reach the full performance potential because these types of facts have not been thoroughly labored out.
The host crystal is far more than just a way to repair the laser-Lively ions at specific positions in Place. Many Homes on the host material are very important:

All those surfaces that happen to be passed by the laser beam are Commonly either oriented at Brewster's angle or have an anti-reflection coating.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
In 2017, we produced the whole world’s greatest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with incredibly huge emission spectra drives the event of laser diode pumped ultrafast strong-condition lasers. With the rise in pulse Electrical power, peak electrical power, and repetition charge of good-condition lasers, laser crystals will develop to much larger dimensions, greater crystal high quality, and controllable crucial functionality.
It could be oriented for near perpendicular incidence of the laser beam, or at Brewster's angle. It can be fixed in certain good mount which also functions for a heat sink. Greater crystals are generally useful for facet pumping e.g. with substantial-electricity diode bars.
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。
