Laser diodes AlGaAs laser diodes RLD-78MA The RLD-78MA is world’s first mass-produced laser diodes that is manufactured by molecular beam epitaxy. The signalto-noise ratio is stable in comparison to conventional manufacturing techniques. This device is ideal for use in compact disc players. External dimensions (Units: mm) M t y p e Applications Compact disc players Features 1) Signal-to-noise ratio guaranteed over entire operating temperature range. 2) Reduced facet reflection. 3) One-third the dispersion compared with conventional laser diodes. 4) High-precision, compact package.
