Apollo is a second and third harmonics generator designed to work with an amplified femtosecond Ti-Sapphire laser output. Two BBO crystals (type I) are utilized to produce SH and TH outputs with efficiencies summarized in the table below. The unit has three outputs corresponding to ~267 nm, ~400 nm, and ~800 nm. Apollo’s dimensions are 11” x 20” (280 x 508 mm)
