TYPE

NAME

DESCRIPTION

ML1XX21

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 160mW.

ML1XX21 has a real-index-waveguide which improves the

slope efficiency (reduction of the operating current) and the

astigmatic distance.

Also, ML1XX21 has a window-mirror-facet which improves

the maximum output power. That leads to highly reliable and

high-power operation.

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.

Note2: TARGET SPEC /Condition Duty Cycle: less than 50%, pulse width: less than 50ns
