Abstract
Tunable semiconductor laser in red visible spectral range of 670-690 nm is investigated. Swept laser is based on a recently developed traveling wave semiconductor optical amplifier (SOA) of red spectral range as an active element and an acousto-optic tunable filter (AOTF) in an external fiber ring cavity. Tuning band of up to 20 nm, spectral linewidth below 0.04 nm, sweep speed of up to 104 nm/s and CW output power of up to 2.0 mW are obtained. Master-Oscillator Power Amplifier (MOPA) system permitted to increase the output power up to 15 mW with a laser used as a master oscillator and an external SOA - as a power amplifier. We believe the red source may find applications in swept source optical coherence tomography.
