These tables include only the most typical host crystals; many Many others exist, which happen to be considerably less regularly used.

These ions allow the crystal to amplify gentle at the laser wavelength by using stimulated emission, when Power is supplied into the crystal by way of absorption of pump gentle (�?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 changeover cross-sections of pump and laser transitions and also the upper-state life time.

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。

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 used to reliably determine the the best possible crystal Proportions, doping density And maybe values of additional 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。

It is clear click here that diverse programs bring about pretty distinct requirements on laser attain media. Due to this, a broad assortment of various crystals are applied, and producing the right selection is essential for developing lasers with the best possible functionality.
