Listed here you'll be able to post questions and responses. As far as they get approved with the author, they are going to appear above this paragraph together with the writer’s remedy. The author will make a decision on acceptance determined by particular criteria. In essence, The problem has to be of sufficiently wide fascination.

This is straightforward to accomplish: just find the lock icon before the URL within the tackle bar and drag that towards the bookmark toolbar Along with the mouse. In case you discover the bookmark entry much too extended, you may correct-click it to edit the text, e.g. making use of "RP Enc" in lieu 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。
A substantial area high quality is naturally vital. Specifications of surface flatness are frequently a lot better than . This will help to stop both equally scattering losses and wavefront distortions that may degrade the laser's beam good quality. Also, scratch and dig requirements
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。
The host crystal is way more than just a means to fix the laser-Energetic ions at sure positions in Area. Quite a few Homes with the host substance are crucial:
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。
Those people surfaces that happen to be passed from the laser beam are Generally either oriented at Brewster's angle or have an anti-reflection coating.

The medium must have a high transparency (small absorption and scattering) from the wavelength areas of pump and laser radiation, and great optical homogeneity. To some extent, this relies on the quality of the fabric, based on specifics of more info the fabrication course of action.
With That idea, one particular isn't going to need to have an extra saturable absorber crystal, to ensure a single could make much more compact Q-switched laser setups with lower interior parasitic losses. Having said that, undesired Uncomfortable side effects can also occur, which include acquiring unwelcome valence states on the associated ions or Strength transfers.
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。
