These tables incorporate only the most common host crystals; numerous Many others exist, that happen to be less regularly applied.
These ions allow the crystal to amplify light at the laser wavelength by using stimulated emission, when Strength is supplied into the crystal through absorption of pump light (�?optical pumping
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。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and also the higher-point out lifetime.

A superior surface good quality is certainly important. Specifications of floor flatness will often be a lot better than . This can help to stay away from both scattering losses and wavefront distortions which may degrade the laser's beam top quality. Furthermore, scratch and dig specs
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
The host crystal is a lot more than simply a method to fix the laser-Energetic ions at selected positions in space. Quite a few Attributes from the host content are crucial:
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
It is obvious that diverse applications result in extremely distinct demands on laser achieve media. This is why, a broad assortment of different crystals are used, and making the right preference is important for setting up lasers with optimum efficiency.
Unique crystalline components are very diverse about their hardness and also other properties, which establish with which methods And the way quickly they may be Reduce and polished with high quality.
In 2017, we designed the world’s most significant 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 really wide emission spectra drives the development of website laser diode pumped ultrafast reliable-point out lasers. With the rise in pulse energy, peak electrical power, and repetition amount of good-point out lasers, laser crystals will create in the direction of greater measurements, increased crystal high quality, and controllable critical general performance.
With that concept, just one does not will need an extra saturable absorber crystal, to ensure that one particular may well make additional compact Q-switched laser setups with lower inner parasitic losses. Nevertheless, undesired Uncomfortable side effects may also occur, for instance getting undesirable valence states with the involved ions or Electricity transfers.
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。
