This is a snap to accomplish: just locate the lock icon in front of the URL while in the handle bar and drag that towards the bookmark toolbar Along with the mouse. In case you find the bookmark entry as well lengthy, it is possible to ideal-click it to edit the textual content, e.g. employing "RP Enc" instead 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。
g. a skinny disk. As One more case in point, Q-switched lasers achieve the next population density from the higher laser level and therefore are hence extra sensitive to quenching effects and Strength transfer procedures; therefore, a reduced doping density is frequently suitable for these equipment. For top-power lasers, reduce doping densities are sometimes accustomed to limit the density of heat generation, although thin-disk lasers get the job done most effective with really doped crystals. Many laser products do not get to the entire general performance probable mainly because these kinds of particulars haven't been appropriately worked out.
The host crystal is a lot more than just a means to fix the laser-Lively ions at particular positions in House. Many Houses with the host material are very important:
蓝宝�?柱面�?球罩 偏振�?棱镜 红外光学元件 反射�?光学窗口 非球面镜 波片 分光�?制造能力
All those surfaces which happen to be handed via the laser beam are normally possibly oriented at Brewster's angle click here or have an anti-reflection coating.

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。
