High-density optical disk systems with storage capacity of over 10GB are focused on as next DVD system. Several high-density optical disk technologies have been reported, such as cross talk canceller technology, magnet super-resolution technology, and use of higher numerical aperture of objective lens and shorter wavelength light source. We have concentrated our attention to development of the shorter wavelength coherent light source. It is required for the light source to gain continuous wave with low noise and good focusing characteristics, and also pulsed power of over 10mW at frequency of maximum modulation frequency of over 10 MHz.
