Listed here you'll be able to post queries and comments. So far as they get accepted because of the author, they'll look above this paragraph together with the author’s respond to. The writer will make a decision on acceptance depending on selected criteria. Primarily, The difficulty must be of sufficiently broad interest.
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
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。
This is simple to do: just find the lock icon before the URL in the address bar and drag that on the bookmark toolbar Along with the mouse. Just in case you discover the bookmark entry far too prolonged, it is possible to proper-click it to edit the textual content, e.g. employing "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。
Certainly, it is rather desirable that a presented crystal quality is made continuously, Though distinctive laser patterns may have a unique 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。
Some laser crystal products have already been demonstrated exactly where some saturable absorber content is integrated for passive Q switching of the laser.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
Those surfaces which might be more info passed from the laser beam are Commonly possibly oriented at Brewster's angle or have an anti-reflection coating.

The medium ought to have a higher transparency (very low absorption and scattering) inside the wavelength areas of pump and laser radiation, and superior optical homogeneity. To some extent, this is dependent upon the standard of the material, determined by facts of your fabrication method.
With That idea, one particular isn't going to want an extra saturable absorber crystal, in order that one may well make far more compact Q-switched laser setups with reduced interior parasitic losses. Even so, undesirable Negative effects may also take place, which include obtaining undesirable valence states with the associated ions or Electrical power transfers.
