Nd:YLF (with the more precise formula Nd:LiYF4) emission wavelengths are 1053, 1047, 1313, 1324 and 1370 nm. This is a laser material that acts as an alternative to Nd:YAG. The main advantage of Nd:YLF over Nd:YAG is a higher pulse energy at a low (<2 kHz) repetition rate. Other notable differences are weak thermal lensing, a relatively broad fluorescence linewidth and naturally polarized oscillation. Altechna provides Nd:YLF crystals selected to have low inhomogeneity over the whole aperture. Crystals with a diameter of 10 mm, length of 120 mm and inhomogeneity of 0.1-0.3×10-5 are available.
- Low inhomogeneity
- Apertures up to 20 mm
- Length up to 120 mm
- Barrel side can be optimized for better heat handling
