3-ND11YLF-4412 - Nd(1,1%):YLF Laser Crystal, 4 x 4 x 12 mm, AR/AR@(790-810)&(1047-1053) nm

Nd:YLF (more precise formula is Nd:LiYF₄) emission wavelengths are 1053, 1047, 1313, 1324, and 1370nm. It is laser material alternative to Nd:YAG . Main Nd:YLF advantage over Nd:YAG is higher pulse energy at low (<2kHz) repetition rate. Other differences are also worth to mention: weak thermal lensing, relatively broad fluorescence linewidth and naturally polarized oscillation. Laserand provides Nd:YLF crystals which are selected to have low inhomogeneity over all aperture. Crystals with diameter 10mm, length 120mm and inhomogeneity ~ 0.1-0.3 * 10-5 are available.
