The most common laser-Lively rare earth ions and host media along with some regular emission wavelengths are demonstrated in the next table:
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。
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 concentration from the get medium are most useful rely upon various components. The readily available pump supply (sort of laser diode or lamp) as well as the envisaged pumping arrangement are essential elements, but the fabric by itself also has some influence. Such as, titanium–sapphire lasers should be pumped with large intensities, for which the shape of the transversely cooled rod, operated with fairly small pump and laser beam diameter, is much more suitable than e.
GWU delivers all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) using a broad a number of requirements. Aside from the very well-recognized products, ground breaking crystals with superb Attributes like Yb:CALGO can open up new horizons for demanding laser apps. Regardless of regardless of whether unique items for R & D purposes are expected or Expense-economical quantities in modest, medium or massive batches with in-time delivery to the production line are essential: GWU’s focused support helps you to locate the very best core parts for your personal application.
A high surface area excellent is of course crucial. Specifications of surface area flatness in many cases are much better than . This assists in order to avoid the two scattering losses more info and wavefront distortions which could degrade the laser's beam excellent. Also, scratch and dig specs
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。
Laser modeling and simulation may be used to reliably figure out the ideal crystal dimensions, doping density And maybe values of extra parameters.
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。
All those surfaces which might be passed via the laser beam are Typically possibly oriented at Brewster's angle or have an anti-reflection coating.
Distinctive crystalline products are certainly different concerning their hardness and various Houses, which ascertain with which solutions And exactly how easily they may be Slice and polished with good quality.
The medium ought to have a superior transparency (very low absorption and scattering) inside the wavelength locations of pump and laser radiation, and very good optical homogeneity. To some extent, this is determined by the quality of the material, based on details on the fabrication process.
It could be oriented for close to perpendicular incidence of your laser beam, or at Brewster's angle. It might be fastened in certain stable mount which also functions to be a warmth sink. Much larger crystals are often employed for aspect pumping e.g. with substantial-electricity diode bars.
