ML1XX27 is a high-power, high-efficient AlGaInP semiconductor laser from Mitsubishi Electric that provides a stable, single transverse mode oscillation with emission wavelength of 658nm and standard pulse light output of 350mW. ML1XX27 has a real-index-waveguide which improves the slope efficiency (reduction of the operating current) and the astigmatic distance. Also, ML1XX27 has a window-mirror-facet which improves the maximum output power. That leads to highly reliable and high-power operation at 75 °C.
The ML101J27 is a high‑efficiency AlGaInP semiconductor laser diode designed for optical information systems such as portable high‑density optical disc drives and rewritable DVD drives. It delivers a stable single‑transverse‑mode output at a typical wavelength of 658 nm.
Key specifications include a 350 mW pulse output, 0.95 W/A slope efficiency, 660 nm typical peak wavelength, and a threshold current of 80 mA. The device is rated for case temperatures from –10 °C to +75 °C and includes safety recommendations for redundancy and malfunction‑prevention designs.
