This is simple to do: just discover the lock icon before the URL during the address bar and drag that on the bookmark toolbar with the mouse. In the event you discover the bookmark entry much too lengthy, it is possible to correct-click on it to edit the text, e.g. utilizing "RP Enc" as an alternative to "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 thin disk. As A further instance, Q-switched lasers access a higher inhabitants density within the upper laser stage and they are consequently far more delicate to quenching consequences and Power transfer processes; consequently, a reduced doping density is frequently suitable for these products. For top-ability lasers, lower doping densities tend to be used to limit the density of heat technology, although slender-disk lasers do the job finest with remarkably doped crystals. Quite a few laser solutions tend not to get to the comprehensive general performance probable mainly because this sort of particulars haven't been effectively labored out.
Some laser crystal supplies are actually demonstrated the place some saturable absorber product is incorporated for passive Q switching of a laser.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
For quasi-three-amount laser get media and even three-stage achieve media, 1 normally should limit the size to a worth that's too limited for efficient pump absorption, as reabsorption outcomes would in any other case spoil the performance. For aspect pumping, more concerns appear into Participate in; Apart from successful pump absorption, it is important to obtain a suitable spatial shape on the get profile.
Distinctive crystalline resources are incredibly distinctive regarding their hardness click here and various Homes, which identify with which strategies and how simply they are often Lower and polished with top quality.
The medium should have a superior transparency (lower absorption and scattering) within the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this is dependent upon the quality of the material, based on specifics of your fabrication approach.
Using our advertising and marketing deal, you may Screen your symbol, additional underneath your product or service description, and these will been noticed by quite a few photonics professionals.
激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
