This is simple to try and do: just find the lock icon in front of the URL from the address bar and drag that on the bookmark toolbar with the mouse. In case you find the bookmark entry much too lengthy, it is possible to right-click it to edit the text, e.g. making use of "RP Enc" in place 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。
Certainly, it is vitally fascinating that a presented crystal top quality is made regularly, Whilst unique laser types can have another sensitivity to substance 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。
Laser modeling and simulation can be used to reliably ascertain the optimum crystal Proportions, doping density and possibly 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-three-level laser acquire media or even 3-level attain media, one particular usually really should limit the duration to a value which happens to be way too short for successful pump absorption, as reabsorption effects would usually spoil the overall performance. For aspect pumping, additional issues appear into Perform; Moreover effective pump absorption, it can be crucial to obtain a suitable spatial shape in the achieve profile.
Various more info crystalline elements are incredibly distinctive concerning their hardness together with other properties, which establish with which methods And the way conveniently they are often cut and polished with high quality.
