The Sony SLD303V is a gain‑guided, high‑power laser diode fabricated by MOCVD. It delivers up to 500 mW radiant power and is intended for solid‑state laser excitation and medical use. The device features a small operating current, high output power, and a GaAlAs double‑heterostructure.
The datasheet lists absolute maximum ratings, pin configuration, optical and electrical characteristics, and detailed graphs of power, wavelength, and efficiency versus current and temperature. Safety precautions emphasize the need for eye protection and infrared‑blocking goggles when handling the laser beam.
