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 get medium are most beneficial depend upon many aspects. The offered pump supply (form of laser diode or lamp) along with the envisaged pumping arrangement are essential elements, but the fabric itself also has some impact. Such as, titanium–sapphire lasers should be pumped with significant intensities, for which the form of a transversely cooled rod, operated with relatively modest pump and laser beam diameter, is more ideal than e.

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。
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。
The host crystal is a lot more than simply a method to repair the laser-active ions at specific positions in Place. Many Qualities in the host substance are crucial:

For quasi-a few-degree laser gain media or even 3-level get media, a single often should Restrict the length to a price that is far too short for productive pump absorption, as reabsorption consequences would in any other case spoil the general performance. For side pumping, added criteria come into Perform; In addition to effective pump absorption, it can be crucial to obtain a suitable spatial form with the attain profile.
