This is not hard to carry out: just find the lock icon in front of the URL within the handle bar and drag that to the bookmark toolbar with the mouse. In case you find the bookmark entry far too prolonged, it is possible to suitable-click on it to edit the text, e.g. utilizing "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。
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。
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。
A handful of laser crystal elements are actually shown where some saturable absorber materials is integrated for passive Q switching of the laser.
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。
It is clear that unique applications bring on quite various demands on laser acquire media. This is why, a wide variety of different crystals are applied, and creating the right option is important for setting up lasers with the best possible functionality.

The medium ought to have a significant transparency (reduced absorption and scattering) during the wavelength areas of pump website and laser radiation, and superior optical homogeneity. To some extent, this depends upon the quality of the material, determined by information of the fabrication system.
With that concept, 1 will not require a further saturable absorber crystal, to ensure that one may possibly make a lot more compact Q-switched laser setups with lower inside parasitic losses. However, unwanted Unwanted effects could also manifest, like getting undesired valence states from the included ions or Power transfers.
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。
