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。

为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。

Also, some adaptability is shed in experiments if a person simply cannot Check out absorbers with distinctive thickness or doping focus, for instance, with no exchanging the laser crystal by itself.

Which geometry, dopant and doping concentration on the achieve medium are most beneficial depend upon many variables. The offered pump supply (kind of laser diode or lamp) and also the envisaged pumping arrangement are important aspects, but the material alone also has some affect. For instance, titanium–sapphire lasers should be pumped with substantial intensities, for which the form of the transversely cooled rod, operated with fairly little pump and laser beam diameter, is more ideal than e.

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。

A number of laser crystal supplies are demonstrated the place some saturable absorber product is incorporated for passive Q switching of the laser.

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-level laser gain media or maybe 3-amount achieve media, a single often should Restrict the duration to a price which is also short for successful pump absorption, as reabsorption effects would if not spoil the performance. For side pumping, more considerations come into Engage in; Other than efficient pump absorption, it is crucial to acquire an acceptable spatial condition from the obtain profile.

Different crystalline supplies are really different concerning their hardness as well as other Qualities, which determine with which solutions And just how quickly they are often Lower and polished with good quality.

GWU-Lasertechnik has more than thirty a long time of encounter in distributing laser crystals. Choose GWU to reap the benefits of our check here large information and in-discipline experience!

Working with our marketing offer, you'll be able to Display screen your emblem, even further below your merchandise description, and these will been found by numerous photonics industry experts.

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。
