Laser Crystal for Dummies
Blog Article
These tables incorporate only the most common host crystals; several others exist, which happen to be a lot less regularly made use of.
Below you'll be able to post thoughts and feedback. So far as they get recognized through the writer, they will look higher than this paragraph together with the creator’s solution. The author will choose acceptance dependant on certain criteria. Basically, the issue has to be of adequately broad curiosity.
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
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 carry out: just discover the lock icon before the URL from the deal with bar and drag that to the bookmark toolbar While using the mouse. Just in case you find the bookmark entry far too extended, you could proper-click on it to edit the textual content, e.g. making use of "RP Enc" rather than "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。
Not surprisingly, it is very desirable that a given crystal top quality is developed persistently, While diverse laser types may have a special sensitivity to material parameters.
g. a skinny disk. As A different example, Q-switched lasers access a higher inhabitants density while in the upper laser degree and they are for that reason more sensitive to quenching effects and Strength transfer procedures; consequently, a decreased doping density is often appropriate for these equipment. For high-electrical power lasers, decreased doping densities tend to be accustomed to limit the density of warmth technology, although skinny-disk lasers operate most effective with highly doped crystals. Numerous laser merchandise tend not to get to the total functionality likely mainly because these facts have not been correctly labored out.
Laser modeling and simulation can be employed to reliably decide the optimum crystal dimensions, doping density And maybe values of added parameters.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
For quasi-3-degree laser acquire media or even a few-stage achieve media, a single frequently needs to Restrict the length to a worth and that is also brief for economical pump absorption, as reabsorption outcomes would in any other case spoil the performance. For side pumping, supplemental issues arrive into play; Aside from economical pump absorption, it is crucial to obtain an appropriate spatial condition of the obtain profile.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
For numerous factors, composite crystals have gotten preferred. These Use a spatially various chemical composition and may be produced with Specific designs.
It could be oriented for close to perpendicular incidence with the laser beam, or at Brewster's angle. It here can be set in certain good mount which also acts as being a heat sink. Much larger crystals are usually used for side pumping e.g. with large-electricity diode bars.
