| MITSUBISHI LASER DIODES ML6XX28 SERIES FOR OPTICAL INFORMATION SYSTEMS TYPE NAME DESCRIPTION ML60128R, ML601J28 FEATURES * Output 60mW (CW), 75mW (pulse) * Small astigmatic distance * Low operation current APPLICATION CD-R/RW Drive MD Drive 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.
