RLD2WMNV1
This is monolithic type single mode 2wavelength laser diode. With our original technology, realized low threshold current
and excellent temperature characteristic. This laser diode is suitable for DVD-ROM and DVD-player.
zApplications
DVD-ROM
DVD player
zFeatures
1) Optimization of a strained multi quantum well realizes
the reduction in threshold current, and the good
temperature characteristic.
2) Low threshold current.
785mm : 18mA (Tc=25°C)
655mm : 20mA (Tc=25°C)
3) Low noise is realized by high frequency modulation
(BU9369FVM)element.
4) Emission point distance : 110µm
