NAME
This type is under development. Therefore, please note that this data sheet may be changed without any notice.
DESCRIPTION
ML1XX27 is a high-power, high-efficient AlGaInP
semiconductor laser which 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.

Note1: The maximum rating means the limitation over which the laser should not be operated even instant time.
This does not mean the guarantee of its lifetime. As for the reliability, please refer to the reliability report issued by
Quality Assurance Section, HF & Optical Semiconductor Division, Mitsubishi Electric Corporation.
