Conoscopic interference of polarized light for the white‐light and LPS‐7,5Volts direct current semiconductor laser (Green light) with wavelength at 532 nm in (Ca 0.28 Ba 0.72 ) x (Sr 0.60 Ba 0.40 ) 1‐x Nb 2 O 6 crystals were observed with the beams transmitting along optical‐axes and deflection optical‐axes from 0 to 140°. Endo‐exo variation from looseness to tightness of conoscopic interference patterns were analyzed in theory. A hyperbolic black cross of interference patterns were observed as well as its formation process was proposed in this paper. Also, the inferences of the birefringence with different Ca 2+ ‐doped were obtained in this investigation. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
