Low power red laser diode
RLD65MPT4
RLD65MPT4
Glass-less structure Red Laser.
Low Ith & good temperature characteristics made by suitability of Multi Quantum Well.
zApplications
DVD-ROM
COMBINATION Drive
Sensors
zFeatures
1) The 10mW of the maximum rating corresponding to
DVD-RAM read.
2) Optimization of a strained multi quantum well realizes
the reduction in threshold current, and the good
temperature characteristic.
3) Low threshold current : 25mA (TC=25°C).
