Ultrashort-Pulse Generation from High-Power Diode Arrays by Using IntracavityOptical Nonlinearities. (Reannouncement with New Availability Information)

摘要

A 40-stripe diode array was actively mode locked in an external cavity containinga single-mode optical fiber and a six-prism sequence to provide self-phase-modulation and tunable dispersion compensation. By making the total cavity group-velocity dispersion strongly negative, a solitonlike pulse-shaping process could be created. Pulses as short as 650 fs with a time-bandwidth product of 0.47 were generated. This study extends new techniques developed for mode locking solid-state lasers to diode-based systems....Mode-locking, Subpicosecond, Optical pulse generation.
