Does anyone have experience in doubling 460 nm using the DCC#4 BBO in a Continuum ND6000 Dye Laser+doubling unit to produce tunable radiation around 230 nm? I would like to generate tunable radiation around 230 nm by doubling 460 nm using the Continuum auto-tracking system and would like to know the performance of the auto-tracker when using 460 nm radiation (Coumarin 460) and its second harmonic. Thanks. Luis Banares
