Abstract

Two infrared diode lasers, with one low reflectance facet of 4.5% or 0.1% have been evaluated in an external cavity diode laser (ECDL) with frequency-shifted feedback, with the aim of generating large frequency bandwidth superfluorescent output. A feedback level dependent linewidth broadening up to 750 MHz and 6 GHz respectively, has been observed for single chip mode operation. Both systems show multiple chip mode operation, with increasing frequency-shifted feedback, increasing in bandwidth to greater than 1 THz. The onset of multiple chip mode operation can be suppressed to higher levels of frequency-shifted feedback by the use of a diffraction grating rather than an external mirror in the ECDL.
