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 not hard to perform: just find the lock icon in front of the URL during the deal with bar and drag that to your bookmark toolbar Using the mouse. In the event you discover the bookmark entry too prolonged, you could correct-click it to edit the text, e.g. employing "RP Enc" in lieu of "RP Photonics Encyclopedia".

GWU presents all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) which has a wide range of requirements. Moreover the properly-proven materials, innovative crystals with outstanding Attributes like Yb:CALGO can open new horizons for demanding laser applications. No matter whether unique items for R & D functions are demanded or Value-effective quantities in little, medium or large batches with in-time shipping for the output line are necessary: GWU’s committed services helps you to locate the very best core parts for your application.

Certainly, it is vitally attractive that a supplied crystal good quality is developed constantly, Despite the check here fact that diverse laser patterns might have a unique sensitivity to materials 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。

Several laser crystal products are already shown exactly where some saturable absorber substance is included for passive Q switching of a 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。

For quasi-three-degree laser gain media or maybe three-amount achieve media, 1 normally should Restrict the length to a price that is far too brief for economical pump absorption, as reabsorption results would if not spoil the functionality. For facet pumping, extra things to consider occur into Participate in; In addition to productive pump absorption, it is important to obtain a suitable spatial shape on the get profile.

Unique crystalline components are quite various about their hardness together with other Qualities, which identify with which procedures and how easily they can be cut and polished with top quality.

For a variety of factors, composite crystals are getting to be preferred. These have a spatially varying chemical composition and might be created with Specific shapes.

It might be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It could be mounted in a few strong mount which also acts to be a warmth sink. Much larger crystals usually are employed for side pumping e.g. with high-power diode bars.

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。
