Laser crystals are optical crystals �?normally one crystals (monocrystalline optical materials) �?which might be utilized as obtain media for stable-point out lasers. Typically, They can be doped with either trivalent exceptional earth ions or transition metal ions.
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 focus of your achieve medium are most beneficial depend upon many aspects. The available pump resource (type of laser diode or lamp) along with the envisaged pumping arrangement are important variables, but the fabric itself also has some affect. For example, titanium–sapphire lasers need to be pumped with superior intensities, for which the form of the transversely cooled rod, operated with comparatively compact pump and laser beam diameter, is more acceptable than e.
GWU delivers all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) by using a broad range of specifications. Moreover the nicely-recognized components, impressive crystals with excellent Attributes like Yb:CALGO can open up new horizons for demanding laser purposes. Regardless of no matter whether person items for R & D uses are required or Expense-successful quantities in compact, medium or big batches with in-time shipping and delivery to the generation line are essential: GWU’s committed assistance helps you to find the most effective core components for your application.
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 handful of laser crystal products are actually shown wherever some saturable absorber product is integrated for passive Q switching of a laser.

Distinct crystalline components are certainly distinct regarding their hardness along with other properties, which decide with which strategies and how effortlessly they may be Slice and polished with good quality.
In 2017, we formulated the world’s largest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with very large emission spectra drives the development of laser diode pumped ultrafast stable-point out lasers. With the increase in pulse Electrical power, peak electricity, and repetition price of good-condition lasers, laser crystals will produce towards more substantial dimensions, greater crystal excellent, and website controllable key effectiveness.
It could be oriented for around perpendicular incidence in the laser beam, or at Brewster's angle. It could be fastened in some good mount which also functions to be a heat sink. Greater crystals are often employed for side pumping e.g. with superior-energy diode bars.
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。
