12 W peak-power 10ps duration optical pulse generation by gain switching of a single-transverse-mode GaInN blue laser diode

Abstract

We have generated optical pulses at 405nm from a single-transverse-mode GaInN blue laser diode under intensive gain-switching operation with a minimum pulse duration of less than 8ps. The maximum optical peak power was as high as 12W with a pulse width of 10ps. The peak power obtained is the highest value for optical pulses ever generated from a single transverse-mode GaInN laser diode.
