These tables contain only the commonest host crystals; lots of Other individuals exist, which might be a lot less routinely utilized.
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。
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
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 as well as the higher-state life span.
GWU offers all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) which has a broad a number of specs. Apart from the effectively-established elements, ground breaking crystals with exceptional Qualities like Yb:CALGO can open up new horizons for demanding laser apps. Irrespective of regardless of whether particular person items for R & D reasons are needed or Value-economical quantities in modest, medium or big batches with in-time supply for that production line are essential: GWU’s focused support really helps to locate the very best core elements in your software.
Obviously, it is rather attractive that a given crystal quality is produced consistently, although distinctive laser designs may have a special sensitivity to product parameters.
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 can be utilized to reliably determine the optimum crystal Proportions, doping density and possibly values of extra parameters.
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。
For quasi-a few-amount laser obtain media or perhaps 3-amount get media, 1 frequently must Restrict the duration to a value which is far too quick for economical pump absorption, as reabsorption outcomes would if not spoil the effectiveness. For side pumping, more concerns appear into Perform; Apart from successful pump absorption, it's important to acquire a suitable spatial shape with the gain profile.

The medium must have a higher transparency (lower absorption and scattering) inside the wavelength regions of pump and laser radiation, and superior optical homogeneity. To some extent, this will depend on the quality of the fabric, determined by aspects on the fabrication procedure.
Working with our marketing offer, you may Show your symbol, more down below check here your merchandise description, and these will been noticed by quite a few photonics experts.
