The commonest laser-Lively uncommon earth ions and host media together with some regular emission wavelengths are revealed in the subsequent desk:
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
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。
Which geometry, dopant and doping concentration with the acquire medium are most useful count on quite a few variables. The readily available pump supply (sort of laser diode or lamp) along with the envisaged pumping arrangement are essential components, but the fabric alone also has some affect. Such as, titanium–sapphire lasers ought to be pumped with higher intensities, for which the shape of the transversely cooled rod, operated with reasonably smaller pump and laser beam diameter, is much more appropriate than e.
GWU provides all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) that has a wide variety of specs. In addition to the perfectly-recognized elements, innovative crystals with remarkable Attributes like Yb:CALGO can open up new horizons for demanding laser purposes. Regardless of irrespective of whether specific items for R & D purposes are needed or Price-effective figures in smaller, medium or substantial batches with in-time supply for the output line are needed: GWU’s dedicated provider really helps to find the most effective core elements for your personal application.
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。
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 considerably more than simply a means to repair the laser-active ions at specified positions in Area. Several Houses in the host product 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。

For several motives, composite crystals are getting to be common. These Use a spatially varying chemical composition and might be produced with Exclusive shapes.
It may click here be oriented for in close proximity to perpendicular incidence on the laser beam, or at Brewster's angle. It may be fastened in some stable mount which also acts to be a warmth sink. Larger sized crystals are frequently used for aspect pumping e.g. with superior-electricity 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。
