Right here you could post questions and feedback. As far as they get accepted by the creator, they may show up previously mentioned this paragraph together with the creator’s response. The author will determine acceptance dependant on sure standards. Primarily, The difficulty needs to be of sufficiently wide interest.
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
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。
This is easy to try and do: just find the lock icon in front of the URL in the deal with bar and drag that to your bookmark toolbar Together with the mouse. In case you locate the bookmark entry also extensive, it is possible to ideal-click it to edit the textual content, e.g. working with "RP Enc" in lieu of "RP Photonics Encyclopedia".
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
Certainly, it is vitally desirable that a supplied crystal excellent is developed persistently, Though various laser designs might have a unique sensitivity to content parameters.
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 materials happen to be shown in which some saturable absorber product 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。
For quasi-3-level laser attain media or maybe 3-stage attain media, just one normally needs to Restrict the duration to a worth and that is also limited for productive pump absorption, as reabsorption consequences would otherwise spoil the performance. For side pumping, supplemental things to consider appear into Participate in; Moreover efficient pump absorption, it is important to acquire an appropriate spatial form on the gain profile.

In 2017, we produced the world’s premier Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with particularly broad emission spectra drives the event of laser diode pumped ultrafast solid-state lasers. With the increase in pulse Electricity, peak ability, and repetition price of strong-condition lasers, laser crystals will establish in the direction of more substantial dimensions, bigger crystal high quality, and controllable crucial click here effectiveness.
It could be oriented for in the vicinity of perpendicular incidence from the laser beam, or at Brewster's angle. It may be mounted in a few stable mount which also functions to be a warmth sink. Larger sized crystals are usually used for side pumping e.g. with high-power diode bars.
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。
