DVD-ROM / player single mode 2wavelength
laser diode
RLD2WMUV2
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.
785nm : 18mA (Tc=25°C)
655nm : 20mA (Tc=25°C)
3) Low noise is realized by high frequency modulation
(BU9369FVM)element.
4) Emission point distance : 110µm
