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。
This is not difficult to complete: just discover the lock icon before the URL within the handle bar and drag that for the bookmark toolbar Along with the mouse. In case you find the bookmark entry way too long, you'll be able to suitable-simply click it to edit the textual content, e.g. using "RP Enc" as an alternative to "RP Photonics Encyclopedia".
GWU gives all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) by using a broad selection of requirements. Aside from the properly-proven materials, revolutionary crystals with excellent Attributes like Yb:CALGO can open up new horizons for demanding laser programs. Regardless of regardless of whether person parts for R & D reasons are needed or Charge-productive quantities in tiny, medium or big batches with in-time shipping for the production line are wanted: GWU’s dedicated provider really helps to find the ideal Main components on your software.
A high surface area excellent is of course crucial. Specs of area flatness will often be better than . This aids in order to avoid both of those scattering losses and wavefront distortions which could degrade the laser's beam good quality. Also, scratch and dig requirements
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 handful of laser crystal components are actually shown in which some saturable absorber product is incorporated for passive Q switching of a laser.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
It is apparent that various programs bring about quite unique prerequisites on laser attain media. Due to this, a wide array of different crystals are employed, and producing the correct option is important for developing lasers with ideal performance.

In 2017, we designed the globe’s biggest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with very vast emission spectra drives the event of laser diode read more pumped ultrafast stable-point out lasers. With the rise in pulse energy, peak energy, and repetition charge of reliable-condition lasers, laser crystals will produce toward much larger measurements, increased crystal excellent, and controllable essential effectiveness.
There exists a wide array of crystalline media, that may be grouped in accordance to big atomic constituents 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。
