BiBO SPDC Crystals

BiBO SPDC Crystals
BiBO SPDC Crystals

 Pump wavelength range: 350 - 800 nm.
  Common pumps:
   ~ 390 - 415 nm (Diode lasers, Ti:Sapphire lasers)
   ~ 351 - 355 nm (THG of Nd: lasers)

Standard crystals are designed for Type I degenerate SPDC
  Half opening angle between signal/idler: 3o

Crystals for the opening angle = 0o (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.
