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 difficult to carry out: just locate the lock icon in front of the URL from the handle bar and drag that towards the bookmark toolbar Using the mouse. In case you find the bookmark entry also extended, you'll be able to appropriate-click on it to edit the text, e.g. utilizing "RP Enc" as an alternative to "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。
A substantial surface area high quality is certainly significant. Specs of area flatness in many cases are much better than . This helps to stop each scattering losses and wavefront distortions which often can degrade the laser's beam quality. Moreover, scratch and dig technical specs
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。
Laser modeling and simulation can be employed to reliably figure out the ideal crystal Proportions, doping density And maybe values of further 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。
It is obvious that distinctive applications produce really different needs on laser attain media. Due to this, a broad vary of different crystals are utilised, and making the correct alternative is important for developing lasers with the best possible general performance.

The medium must have a large transparency (minimal absorption and scattering) inside the wavelength regions of pump and laser radiation, and good optical homogeneity. To some extent, this depends upon the standard of the fabric, determined by specifics from the fabrication process.
Making use of our marketing package, you could Exhibit your here emblem, additional down below your merchandise description, and these will been noticed by lots of photonics pros.
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。
