The most common laser-active uncommon earth ions and host media together with some regular emission wavelengths are demonstrated in the following desk:
These ions permit the crystal to amplify light in the laser wavelength by means of stimulated emission, when Strength is provided to the crystal by means of absorption of pump light (�?optical pumping
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 accomplish: just locate the lock icon before the URL inside the tackle bar and drag that to the bookmark toolbar Together with the mouse. Just in case you find the bookmark entry also extensive, you'll be able to suitable-simply click it to edit the textual content, e.g. applying "RP Enc" as opposed 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。
Of course, it is very attractive that a supplied crystal excellent is developed persistently, Though different laser layouts may have a different sensitivity to product 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。
Some laser crystal supplies are shown where some saturable absorber substance is integrated for passive Q switching of the laser.
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。
People surfaces which might be passed by the laser beam are Ordinarily both oriented at Brewster's angle or have an anti-reflection coating.

The medium must have a high transparency (small more info absorption and scattering) from the wavelength regions of pump and laser radiation, and superior optical homogeneity. To some extent, this will depend on the quality of the fabric, determined by information from the fabrication course of action.
With That idea, one particular won't will need an additional saturable absorber crystal, to ensure that 1 might make much more compact Q-switched laser setups with lower interior parasitic losses. On the other hand, undesired Uncomfortable side effects may additionally happen, such as acquiring unwanted valence states of your concerned ions or Vitality 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。
