These ions empower the crystal to amplify light-weight at the laser wavelength by means of stimulated emission, when Electrical power is supplied into the crystal by means of absorption of pump light-weight (�?optical pumping

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。

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 focus on the get medium are most useful rely upon a number of factors. The offered pump source (style of laser diode or lamp) along with the envisaged pumping arrangement are important variables, but the fabric itself also has some influence. One example is, titanium–sapphire lasers need to be pumped with large intensities, for which the shape of the transversely cooled rod, operated with relatively tiny pump and laser beam diameter, is more suitable than e.

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 most doable doping concentration can rely strongly on the host material and its fabrication strategy.

激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。

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。

People surfaces that are passed via the laser beam are Commonly either oriented at Brewster's angle or have an anti-reflection coating.

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。

In 2017, we developed the world’s major Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with particularly check here vast emission spectra drives the event of laser diode pumped ultrafast stable-condition lasers. With the increase in pulse Power, peak power, and repetition level of solid-condition lasers, laser crystals will acquire towards larger sized dimensions, greater crystal high quality, and controllable crucial efficiency.

There exists a wide array of crystalline media, which can be grouped according to special atomic constituents and crystalline structures. Some essential groups 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。
