The most common laser-Lively rare earth ions and host media together with some common emission wavelengths are shown in the subsequent desk:

This is straightforward to do: just discover the lock icon before the URL in the tackle bar and drag that to the bookmark toolbar Together with the mouse. Just in case you find the bookmark entry also very long, you can proper-click on it to edit the text, e.g. employing "RP Enc" as an alternative to "RP Photonics Encyclopedia".

GWU delivers all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) which has a wide a number of technical specs. Other than the perfectly-recognized resources, modern crystals with fantastic Qualities like Yb:CALGO can open up new horizons for demanding laser apps. Irrespective of no matter whether person pieces for R & D applications are required or Price-economical numbers in small, medium or massive batches with in-time delivery for that production line are essential: GWU’s focused support really helps to locate the greatest Main factors for the application.

A superior surface top quality is of course crucial. Requirements of floor flatness are often better than . This assists in order to avoid equally scattering losses and wavefront distortions which often can degrade the laser's beam excellent. On top of that, scratch and dig technical specs

g. a skinny disk. As Yet another illustration, Q-switched lasers achieve the next population density during the upper laser degree and so are hence a lot more sensitive to quenching outcomes and energy transfer processes; consequently, a decrease doping density is frequently suitable for these products. For top-ability lasers, lower doping densities are sometimes accustomed to Restrict the density of warmth technology, While slim-disk lasers get the job done finest with remarkably doped crystals. Quite a few laser merchandise tend not to reach the full overall performance likely since this kind of aspects have not been correctly worked out.

The host crystal is a lot more than simply a method to repair the laser-Lively ions at specific positions in Place. Many properties of your host materials are essential:

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 as well as three-stage obtain media, one generally has to Restrict the length to a price that is far too brief for successful pump absorption, as reabsorption effects would usually spoil the efficiency. For facet pumping, extra things to consider come into Perform; Moreover efficient pump absorption, it is vital to get an appropriate spatial form with the gain 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。

GWU-Lasertechnik has over 30 a long time of knowledge in distributing laser crystals. Opt for GWU to benefit from our wide knowledge As get more info well as in-subject practical experience!

It could be oriented for in the vicinity of perpendicular incidence of your laser beam, or at Brewster's angle. It might be preset in a few reliable mount which also acts as being a warmth sink. Larger sized crystals tend to be employed for side pumping e.g. with higher-power diode bars.

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。
