ML6XX25 is a high power AlGaAs semiconductor
laser which provides a stable, single transverse
mode oscillation with emission wavelength of
785nm and standard light output of 30mW.
ML6XX25 is produced by the MOCVD crystal
growth method
which is excellent in mass
production and characteristics uniformity . This is
a high -performance , highly reliable , and long
life semiconductor laser.
O High volume production capacity
Built-in monitor photodiode (ML60125R)
APPLICATION
Optical disc drive
