DESCRIPTION
The NDL3321ST and NDL3321SU are AlGaInP 650 nm vis-
ible laser diodes specially developed for DVD and DVD-ROM.
The newly developed Multiple Quantum Well (MQW) LD chip
can achieve low operating current over a wide temperature
range.
Use of a CD package allows easy replacement of conven-
tional 780 nm LDs.
