This is a snap to complete: just discover the lock icon in front of the URL during the deal with bar and drag that into the bookmark toolbar Using the mouse. In the event you locate the bookmark entry as well very long, you could appropriate-click it to edit the textual content, e.g. working with "RP Enc" in lieu of "RP Photonics Encyclopedia".
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。
A substantial area high-quality is of course vital. Requirements of floor flatness are often better than . This helps to stop both scattering losses and wavefront distortions which might degrade the laser's beam top quality. Furthermore, scratch and dig specs
g. a thin disk. As A different instance, Q-switched lasers achieve the next inhabitants density within the higher laser degree and so are hence more sensitive to quenching outcomes and Electrical power transfer processes; hence, a lower doping density is often appropriate for these devices. For prime-energy lasers, reduced doping densities in many cases are utilized to Restrict the density of warmth generation, While skinny-disk lasers do the job greatest with really doped crystals. Many laser solutions don't reach the full efficiency likely since these facts haven't been appropriately labored out.
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。
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
It is obvious that diverse applications produce Laser Crystal quite various requirements on laser acquire media. Due to this, a broad selection of different crystals are made use of, and making the proper decision is important for constructing lasers with ideal overall performance.
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 more than 30 a long time of expertise in distributing laser crystals. Select GWU to gain from our vast expertise As well as in-discipline expertise!
It might be oriented for in the vicinity of perpendicular incidence from the laser beam, or at Brewster's angle. It can be set in some solid mount which also acts like a heat sink. More substantial crystals are often employed for side pumping e.g. with substantial-electricity 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。
