BBO SPDC Crystals
BBO SPDC Crystals BBO SPDC Crystals

Pump wavelength range: 260 - 800 nm.
  Common pumps:
   ~ 390 - 415 nm (Diode lasers, SHG of Ti:Sapphire lasers)
   ~ 342 - 355 nm (THG of Nd:/Yb: lasers), 257 - 266 nm (F
HG 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 directions for Type I: 3o
  Half opening angle between entangled emission directions for Type II: 5o

Crystals for the opening angle = 0o (collinear phase matching) or other angles
  are availble upon request.   

Non-degenerate SPDC crystals are available upon request.
 Common aperture sizes: 5x5 mm, 8x8 mm. OD 1" mounted.
