Explore our SFG Crystal range

Want to learn more about our range? SFG (Sum Frequency Generation) crystals are available in a variety of wavelengths. Using our SFG crystals it is possible to achieve cascaded THG from a 1550-nm SHG crystal, or from a fixed 1550-nm laser and a tunable Ti:sapphire (or similar) laser for tunable green generation.
