These ions empower the crystal to amplify gentle on the laser wavelength through stimulated emission, when Strength is provided for the crystal via absorption of pump light (�?optical pumping

为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。

Which geometry, dopant and doping concentration from the get medium are most advantageous rely upon numerous factors. The readily available pump source (style of laser diode or lamp) as well as the envisaged pumping arrangement are very important variables, but the fabric alone also has some influence. Such as, titanium–sapphire lasers need to be pumped with high intensities, for which the shape of a transversely cooled rod, operated with somewhat little pump and laser beam diameter, is a lot more appropriate than e.

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。

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-three-stage laser achieve media and even a few-degree attain media, 1 typically should limit the duration to a price which is also brief for successful pump absorption, as reabsorption effects would usually spoil the overall performance. For side pumping, additional factors appear into Participate in; besides economical pump absorption, it is necessary to get an appropriate spatial shape of the acquire profile.

Different crystalline supplies are incredibly various regarding their hardness and other Attributes, which figure out with which methods and how very easily they may be Slice and polished with top quality.

The medium should have a high transparency (small absorption and scattering) in the wavelength areas of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is determined by the standard of the check here material, determined by particulars from the fabrication system.

With That idea, just one does not have to have an extra saturable absorber crystal, to ensure that a single may possibly make much more compact Q-switched laser setups with reduce interior parasitic losses. Nonetheless, unwelcome Uncomfortable side effects might also arise, including getting unwanted valence states in the concerned ions or Vitality transfers.
