We can supply Pr:YLF Crystals in various sizes. Praseodymium (Pr3+) is an interesting laser ion that can be used in solid-state lasers in the visible spectral range because of its energy level scheme offering red, orange, green, and dark red spectral regions. Pr3+:YLF is a promising lasing material for direct visible laser generation and ultraviolet laser generation via intracavity second harmonic generation.
