These tables comprise only the most common host crystals; quite a few Other people exist, which happen to be significantly less commonly made use of.

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。
Moreover, some flexibility is shed in experiments if 1 can't try out absorbers with distinct thickness or doping focus, one example is, without the need of exchanging the laser crystal alone.
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
晶体生长 晶体加工 镀膜能�?品质管理 研发能力 新闻中心
A high surface area good quality is certainly essential. Specifications of surface area flatness are sometimes much better than . This allows to avoid each scattering losses and wavefront distortions which might degrade the laser's beam top quality. Furthermore, scratch and dig specs
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 much more than just a way to fix the laser-Lively ions at certain positions in Area. A variety of Qualities on the host check here substance are crucial:
蓝宝�?柱面�?球罩 偏振�?棱镜 红外光学元件 反射�?光学窗口 非球面镜 波片 分光�?制造能力
It is apparent that various applications bring about really diverse demands on laser achieve media. This is why, a broad assortment of different crystals are employed, and producing the correct option is essential for developing lasers with ideal efficiency.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
The medium should have a higher transparency (small absorption and scattering) inside the wavelength locations of pump and laser radiation, and great optical homogeneity. To some extent, this relies on the quality of the fabric, based on information of the fabrication system.
With That idea, one particular isn't going to need to have an extra saturable absorber crystal, to ensure a single might make much more compact Q-switched laser setups with lower inside parasitic losses. Even so, undesirable Unwanted side effects may also come about, including getting undesirable valence states of your concerned ions or energy transfers.
