The most common laser-Lively exceptional earth ions and host media together with some regular emission wavelengths are shown in the following table:
These ions help the crystal to amplify gentle in the laser wavelength by means of stimulated emission, when Vitality is provided towards the crystal through absorption of pump light (�?optical pumping
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。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions in addition to the upper-condition lifetime.
GWU features all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) using a wide range of technical specs. Besides the well-established components, impressive crystals with superb Qualities like Yb:CALGO can open up new horizons for demanding laser purposes. No matter regardless of whether personal items for R & D reasons are essential or Value-productive numbers in small, medium or huge batches with in-time delivery with the manufacturing line are necessary: GWU’s focused support really helps to discover the best core components on your application.
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
The utmost achievable doping focus can count strongly about the host substance and its fabrication strategy.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
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。
For quasi-3-degree laser acquire media and even 3-amount get media, a single often needs to Restrict the size to a price which is too limited for economical pump absorption, as reabsorption outcomes would in any other case spoil the performance. For side pumping, more concerns occur into Perform; Apart from efficient pump absorption, it is important to get an appropriate spatial shape of the obtain profile.
