Applications: - Harmonic Generation (SHG, THG, 4HG, 5HG) of YAG, SHG of Ti: Sapphire and Alexandrite lasers. - Tunable solid-state lasers using OPO (pumped by 355, 532 or 1064 nm) - Efficient UV sources using SHG and SFG of the tunable dye lasers - Autocorrelators (in thin crystals) in picosecond and femtosecond laser systems.
