This is straightforward to complete: just discover the lock icon before the URL while in the address bar and drag that on the bookmark toolbar Using the mouse. Just in case you discover the bookmark entry much too extended, you may correct-click on 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。
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
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。
For quasi-3-level laser gain media or even 3-level attain media, just one usually must Restrict the duration to a price which happens to be far too brief for economical pump absorption, as reabsorption effects would usually spoil the efficiency. For aspect pumping, more concerns arrive into play; Moreover effective pump absorption, it's important to get a suitable spatial shape with the get profile.

In 2017, we developed the earth’s biggest 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 very large emission spectra drives the event of laser diode pumped ultrafast strong-condition lasers. With the increase in pulse Electricity, peak power, and repetition amount of solid-state lasers, laser crystals will create in direction of greater sizes, greater crystal top quality, and controllable essential effectiveness.
It might be oriented for around perpendicular incidence with the laser beam, or at Brewster's angle. It could be fastened in a few reliable mount which also acts as being a heat sink. Bigger crystals are frequently employed for side pumping e.g. with higher-electricity diode more info bars.
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。
