The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and likewise the upper-state lifetime.

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。

活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。

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 method to fix the laser-active ions at specified positions in House. Numerous Homes with the host material are very important:

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-3-degree laser gain media or maybe 3-amount achieve media, 1 normally should Restrict the length to a worth that is much too quick for economical pump absorption, as reabsorption results would usually spoil the efficiency. For facet pumping, additional issues come into Engage in; Other than efficient pump absorption, it is crucial to acquire an acceptable spatial condition of the acquire profile.

GWU-Lasertechnik has much more than thirty years of encounter in distributing laser crystals. Pick GWU to get pleasure from our huge awareness As well as in-discipline knowledge!

You can find a wide range of crystalline media, which can be grouped according to special atomic constituents click here and crystalline constructions. Some significant teams of crystals are:

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。
