文摘
- •
A tunable multiwavelength actively mode-locked fiber ring laser is reported.
- •
Laser is based on polarization and wavelength dependent loss induced in the cavity.
- •
Stable ultrashort pulses of pulsewidth 14 ps are attained at 10 GHz repetition rate.
- •
Simultaneous lasing of 5 wavelengths each with 3-dB bandwidth of 0.2 nm are obtained.
- •
The pulsewidth is stable within 732 fs and peak power fluctuations within 0.16 mW.
