激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
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。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and in addition the upper-condition life time.
GWU presents all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) having a wide selection of specs. In addition to the effectively-recognized resources, ground breaking crystals with outstanding Attributes like Yb:CALGO can open new horizons for demanding laser purposes. No matter whether or not unique items for R & D applications are necessary or Price-productive quantities in tiny, medium or huge batches with in-time delivery for the production line are necessary: GWU’s devoted services helps to locate the most effective core components in your software.
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 One more instance, Q-switched lasers achieve the next population density in the higher laser level and they are for that reason far more sensitive to quenching outcomes and energy transfer processes; for that reason, a reduce doping density is frequently suitable for these units. For high-electric power lasers, reduced doping densities are often utilized to Restrict the density of warmth era, Whilst click here slim-disk lasers perform ideal with extremely doped crystals. Several laser products and solutions usually do not get to the whole performance prospective for the reason that this sort of details haven't been thoroughly worked out.
The host crystal is much more than just a method to repair the laser-active ions at certain positions in House. Several properties from the host materials are important:
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 distinctive purposes result in pretty different demands on laser attain media. For this reason, a wide vary of various crystals are used, and generating the best choice is important for constructing 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。
In 2017, we designed the entire world’s biggest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with very extensive emission spectra drives the development of laser diode pumped ultrafast strong-point out lasers. With the increase in pulse Strength, peak electricity, and repetition charge of stable-state lasers, laser crystals will develop in direction of bigger sizes, larger crystal excellent, and controllable critical general performance.
Working with our marketing deal, you can Screen your brand, further more beneath your products description, and these will been noticed by lots of photonics industry experts.
