The most typical laser-active uncommon earth ions and host media together with some regular emission wavelengths are demonstrated in the next desk:
Right here it is possible to post thoughts and comments. As far as they get accepted from the author, they can appear above this paragraph together with the creator’s solution. The author will decide on acceptance based on certain conditions. Fundamentally, The problem has to be of sufficiently wide desire.

激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
Which geometry, dopant and doping focus of your get medium are most advantageous depend upon many factors. The obtainable pump source (form of laser diode or lamp) as well as the envisaged pumping arrangement are crucial aspects, but the fabric itself also has some impact. As an example, titanium–sapphire lasers ought to be pumped with substantial intensities, for which the shape of a transversely cooled rod, operated with somewhat little pump and laser beam diameter, is much 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 instance, Q-switched lasers achieve an increased population density inside the upper laser stage and so are thus more sensitive to quenching effects and Power transfer processes; therefore, a reduce doping density is often suitable for these equipment. For top-electric power lasers, decreased doping densities in many cases are accustomed to limit the density of heat technology, While skinny-disk lasers get more info function most effective with remarkably doped crystals. A lot of laser items do not get to the complete performance probable since such information haven't been effectively labored out.
A handful of laser crystal products are already shown where by some saturable absorber materials is incorporated for passive Q switching of a laser.
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 that unique apps cause quite distinct needs on laser acquire media. For this reason, a wide selection of different crystals are used, and building the best option is essential for developing lasers with ideal effectiveness.
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。
GWU-Lasertechnik has over 30 a long time of practical experience in distributing laser crystals. Opt for GWU to benefit from our wide knowledge As well as in-subject practical experience!
It could be oriented for around perpendicular incidence in the laser beam, or at Brewster's angle. It may be fixed in a few reliable mount which also acts as a warmth sink. Larger sized crystals tend to be employed for aspect pumping e.g. with higher-power diode bars.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
