| Abstract: | The authors studied temporal optics characteristics about Qptical heads for megnetooptic disk. In maggetooptic disk head, temporal varition of laser intensity will lead to randem distribution of power density along the beam cross -section, and so coused the recording to change, laser variations in polarization, phase and wavelength constitute laser noise and shift P polarization transmission. Under the temporal condition, relative value of the aberration for magnetooptic head optics system, S.D. is no less than 0.82. To obtain a high signal -noise ratio we developed two units of magnetooptic head optics system which are composed of, beam shaping prism and polarized beam spliters with 99.6% anti -reflent reflentivity. |
