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 easy to accomplish: just locate the lock icon before the URL within the deal with bar and drag that to your bookmark toolbar Using the mouse. In the event you discover the bookmark entry much too long, you are able to appropriate-click on it to edit the textual content, e.g. applying "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。
Naturally, it is very appealing that a specified crystal top quality is manufactured continually, Whilst diverse laser designs might have a special sensitivity to content 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。
The host crystal is much more than simply a means to repair the laser-active ions at selected positions in Area. A number of Homes of the host substance are essential:
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。

The medium should have a higher transparency (minimal absorption and scattering) inside the wavelength regions of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends on the quality of the fabric, based on facts with the fabrication course of action.
With That idea, a single will not want an additional more info saturable absorber crystal, to make sure that one particular might make extra compact Q-switched laser setups with decreased inner parasitic losses. However, undesired Negative effects may also arise, such as acquiring unwelcome valence states from the included ions or Power transfers.
