BBO SPDC Crystals

Pump wavelength range: 260 - 800 nm.
Common pumps:
~ 390 - 415 nm (Diode lasers, SHG of Ti:Sapphire lasers)
~ 343 - 355 nm (THG of Nd:/Yb: lasers), 260 - 266 nm (FHG of Nd:/Yb: lasers)
~ 775 nm (Ti:Sapphire lasers, SHG of Er: lasers)
Standard crystals are designed for Type I or Type II degenerate SPDC
Half opening angle between signal/idler for Type I: 3^o
Half opening angle between conjugated directions for Type II: 5^o
Crystals for the opening angle = 0^o (collinear phase matching) or other angles
are availble upon request.
Non-degenerate SPDC crystals are available upon request.
Aperture sizes: 5x5 mm, 8x8 mm. OD 1" mounted.
