Hologram Lasers GH6D305S5A GH6D305S5A Self-oscillating Type, 3mm Thickness Resin Stem Red Hologram Laser for DVD-Video (Under development) Outline Dimensions (1) Employing a self-oscillating laser chip enables a compact and low cost pick-up. It eliminates the need for radio frequency modulation circuit and related resistors/shields. (2) Insert frame structure enables super-thin package(3.0mm thickness) (3) With built-in high speed response OPIC (MIN. 40MHz) (4) With built-in beam splitter and diffraction grating OPIC : (Optical IC) is a trademark of SHARP Corporation. An OPIC consists of a light-detecting element and a signal-processing circuit integrated onto a single chip.
