Right here you are able to submit questions and feedback. So far as they get accepted because of the writer, they are going to surface over this paragraph along with the creator’s answer. The writer will determine acceptance depending on certain criteria. Primarily, The problem has to be of adequately wide desire.
Laser crystals are optical crystals �?generally one crystals (monocrystalline optical materials) �?which are made use of as attain media for strong-condition lasers. Typically, They can be doped with both trivalent exceptional earth ions or transition steel ions.
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
This is not hard to complete: just discover the lock icon before the URL within the tackle bar and drag that to the bookmark toolbar Together with the mouse. In case you locate the bookmark entry far too lengthy, you'll be able to correct-click on it to edit the textual content, e.g. employing "RP Enc" instead 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。
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。
The maximum achievable doping concentration can depend strongly over the host content and its fabrication method.
Laser modeling and simulation can be utilized to reliably figure out the the best possible crystal Proportions, doping density and possibly values of extra parameters.
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-a few-amount laser attain media or maybe 3-level gain media, one normally ought to limit the duration to a value which can be too shorter for successful pump absorption, as reabsorption outcomes would in any other case spoil the efficiency. For facet pumping, added considerations appear into Perform; Other than effective pump absorption, it can be crucial to obtain a suitable spatial shape on the attain profile.

In 2017, we formulated the whole world’s major 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 get more info crystals with really vast emission spectra drives the development of laser diode pumped ultrafast solid-point out lasers. With the rise in pulse Vitality, peak electricity, and repetition price of solid-point out lasers, laser crystals will establish in the direction of bigger dimensions, better crystal good quality, and controllable essential performance.
It might be oriented for in close proximity to perpendicular incidence of your laser beam, or at Brewster's angle. It can be set in a few reliable mount which also functions being a warmth sink. Much larger crystals tend to be used for side pumping e.g. with higher-energy diode 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。
