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。

Which geometry, dopant and doping concentration in the obtain medium are most advantageous depend on a number of factors. The out there pump resource (variety of laser diode or lamp) as well as envisaged pumping arrangement are very important variables, but the material alone also has some affect. As an example, titanium–sapphire lasers need to be pumped with high intensities, for which the shape of a transversely cooled rod, operated with somewhat modest pump and laser beam diameter, is a lot more correct than e.

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。

激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。

The utmost possible doping focus can count strongly about the host material and its fabrication system.

Laser modeling and simulation can be utilized to reliably identify the ideal crystal dimensions, doping here density And perhaps values of additional parameters.

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。

For quasi-three-amount laser obtain media or perhaps 3-degree attain media, one often needs to limit the duration to a value which happens to be too short for efficient pump absorption, as reabsorption consequences would normally spoil the functionality. For aspect pumping, more factors appear into Participate in; In addition to productive pump absorption, it can be crucial to acquire an acceptable spatial condition of the gain profile.

Diverse crystalline materials are certainly various relating to their hardness as well as other Attributes, which decide with which solutions And just how effortlessly they are often cut and polished with good quality.

For many explanations, composite crystals are getting to be well known. These Use a spatially various chemical composition and can be made with Distinctive designs.

It might be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It can be set in some sound mount which also acts as being a heat sink. Bigger crystals are generally utilized for side pumping e.g. with high-power diode bars.
