The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions as well as the upper-point out life span.
GWU features all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) using a wide range of technical specs. Apart from the very well-recognized supplies, impressive crystals with excellent Qualities like Yb:CALGO can open up new horizons for demanding laser applications. Irrespective of whether or not particular person items for R & D uses are essential or cost-effective numbers in smaller, medium or massive batches with in-time supply for your output line are desired: GWU’s devoted services really helps to find the finest Main elements for your personal application.
A large surface high-quality is not surprisingly significant. Technical specs of area flatness tend to be much better than . This assists to prevent both scattering losses and wavefront distortions that may degrade the laser's beam quality. Additionally, scratch and dig technical specs
g. a skinny disk. As A further instance, Q-switched lasers reach a better populace density from the upper laser amount and so are thus additional sensitive to quenching results and Power transfer processes; hence, a reduced doping density is usually appropriate for these products. For high-electrical power lasers, lessen doping densities tend to be accustomed to Restrict the density of heat era, While skinny-disk lasers function best with extremely doped crystals. Numerous laser products and solutions tend not to get to the comprehensive effectiveness possible since this sort of information have not been appropriately worked out.
The host crystal is much more than just a way to fix the laser-Lively ions at specified positions in Room. Numerous Attributes of your host materials are important:
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。
It is clear that distinctive programs bring on incredibly unique requirements on laser attain media. For this reason, a broad vary of various crystals are employed, and producing the proper preference is essential for developing 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 thirty a long click here time of practical experience in distributing laser crystals. Pick out GWU to take pleasure in our extensive knowledge and in-discipline practical experience!
It could be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It can be mounted in a few stable mount which also functions as being a heat sink. Larger sized crystals are frequently utilized for side pumping e.g. with high-electric 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。
