Praseodymium-Doped Yttrium Lithium Fluoride (Pr:YLF) Crystal is a rare laser material that achieves laser emission in the visible spectrum due to the abundant transitions of Pr3+ ions. This enables the generation of blue, green, orange, red, and deep red down-conversion laser outputs. The relative threshold values between two wavelengths significantly influence dual-wavelength laser operation. Modulating the pump power to adjust cavity losses allows for dual-wavelength switching output. Available in various sizes, such as 3x3x6mm and 5x5x12mm, for different applications. Heeger Materials provides Pr:YLF Crystal for advanced laser systems.
