This handbook describes the Sony SLD303XT gain‑guided high‑power laser diode, its flat package with built‑in TE cooler, and its key features such as high output power and low operating current. It lists the diode structure, typical applications in solid‑state laser excitation and medical use, and the absolute maximum ratings.
The document includes detailed optical and electrical characteristics, pin configuration, performance graphs (radiant power vs. current, wavelength vs. temperature), handling precautions, and TE‑cooler specifications. Safety recommendations emphasize the use of infrared‑blocking goggles and other protective equipment when observing the laser beam.
