These tables have only the commonest host crystals; numerous Some others exist, which can be a lot less frequently employed.

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 focus in the obtain medium are most advantageous count on various variables. The obtainable pump resource (form of laser diode or lamp) as well as the envisaged pumping arrangement are essential factors, but the fabric by itself also has some affect. As an example, titanium–sapphire lasers need to be pumped with high intensities, for which the shape of a transversely cooled rod, operated with rather modest pump and laser beam diameter, is more correct 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。

g. a skinny disk. As another illustration, Q-switched lasers get to a higher population density inside the upper laser stage and so are therefore much more sensitive to quenching effects and Vitality transfer processes; thus, a lower doping density is often appropriate for these gadgets. For prime-electricity lasers, decreased doping densities are often utilized to Restrict the density of heat generation, Though skinny-disk lasers function greatest with hugely doped crystals. A lot of laser merchandise tend not to reach the full performance opportunity mainly because these kinds of specifics haven't been appropriately worked out.

A few laser crystal products are already shown exactly where some saturable absorber substance is incorporated for passive Q switching of a 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。

For quasi-3-level laser attain media or even a few-degree gain media, a person usually must Restrict the duration to a price which happens to be way too brief for successful pump absorption, as reabsorption effects would normally spoil the general performance. For aspect pumping, supplemental factors appear into play; Apart from successful pump absorption, it's important to get an acceptable spatial condition here of your acquire profile.

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。

For different factors, composite crystals are becoming popular. These Have got a spatially varying chemical composition and might be produced with Specific designs.

It might be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It could be mounted in a few strong mount which also acts being a warmth sink. More substantial crystals are frequently utilized for side pumping e.g. with superior-ability diode bars.
