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 concentration on the achieve medium are most beneficial rely on numerous aspects. The obtainable pump source (type of laser diode or lamp) and the envisaged pumping arrangement are crucial components, but the material alone also has some affect. For instance, titanium–sapphire lasers should be pumped with significant intensities, for which the form of the transversely cooled rod, operated with somewhat modest pump and laser beam diameter, is more appropriate than e.
GWU delivers all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) that has a wide selection of specifications. In addition to the effectively-set up components, modern crystals with fantastic Homes like Yb:CALGO can open up new horizons for demanding laser programs. Irrespective of irrespective of whether unique items for R & D functions are essential or cost-successful numbers in smaller, medium or huge batches with in-time supply for your generation line are required: GWU’s committed service helps to locate the very best core parts for your personal 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 possible doping concentration can rely strongly on the host substance and its fabrication approach.
Some laser crystal components have been demonstrated where some saturable absorber materials is included for passive Q switching of the laser.
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 apparent that diverse purposes result in really diverse necessities on here laser get media. Due to this, a wide range of various crystals are made use of, and earning the right preference is important for constructing lasers with the best possible effectiveness.
