FOR OPTICAL INFORMATION SYSTEMS
TYPE
NAME
ML60128R, ML601J28
DESCRIPTION
ML6XX28 is a high power AlGaAs semiconductor laser
which provides a stable, single transverse mode oscillation
with emission wavelength of 785nm and standard light output
power of 60mW.
ML6XX28 is produced by a MOCVD crystal growth
method which is excellent in mass production and
characteristics uniformity. This is a high-performance, highly
reliable, and low-operation-current semiconductor laser.
FEATURES
• Output 60mW (CW), 75mW (pulse)
• Small astigmatic distance
• Low operation current

Note1: The maximum rating means the limitation over which the laser should not be operated even instant time,
and 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 Co..
