These tables contain only the most typical host crystals; quite a few Other people exist, which happen to be significantly less routinely used.
These ions allow the crystal to amplify light within the laser wavelength through stimulated emission, when Vitality is equipped on the crystal by way of absorption of pump light-weight (�?optical pumping

This is not hard to accomplish: just discover the lock icon in front of the URL from the address bar and drag that on the bookmark toolbar Using the mouse. In the event you locate the bookmark entry too extended, you could correct-click it to edit the text, e.g. employing "RP Enc" in lieu of "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。
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
Laser modeling and simulation may be used to reliably decide the the best possible crystal dimensions, doping density And maybe values of extra parameters.
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-3-level click here laser acquire media or simply 3-level get media, a single often ought to limit the size to a value and that is as well small for efficient pump absorption, as reabsorption consequences would in any other case spoil the performance. For side pumping, more concerns appear into Participate in; In addition to efficient pump absorption, it is necessary to acquire an acceptable spatial condition of the acquire profile.
Distinctive crystalline resources are extremely distinctive regarding their hardness and other Homes, which ascertain with which techniques And just how effortlessly they are often Slice and polished with good quality.
GWU-Lasertechnik has much more than thirty many years of expertise in distributing laser crystals. Decide on GWU to take pleasure in our wide knowledge As well as in-industry working experience!
Making use of our promoting bundle, you may Screen your logo, even more beneath your solution description, and these will been seen by lots of photonics pros.
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。
