Nd:YLF Crystals, 100 mm Length, c-cut

The emission wavelengths of Nd:YLF are 1053, 1047, 1313, 1324 and 1370 nm. This is a laser material that can replace Nd:YAG. Compared with Nd:YAG, the lower thermal conductivity and weaker negative dn/dT of Nd3+:YLF crystal lead to lower thermal distortion and achieve better output beam quality. Alfa Chemistry offers a selection of Nd:YLF crystals with different specifications.
