Electronically controlled high-speed wavelength-tunable femtosecond soliton pulse generation using acoustooptic modulator

The compact system of electronically controlled highspeed wavelength-tunabl e femtosecond (fs) soliton pulse generation is realized for the first time using a passively mode-locked fs fiber laser, a polarization maintaining op tical fiber, and an acoustooptic (A-O) modulator. The wavelength of the out put pulses can be continuously tuned simply by controlling the input voltag e into the A-O modulator. The wavelength of the soliton pulses can be chang ed at 2.5-mus intervals. Wavelength stabilization, time division wavelength multiplexed soliton pulse generation, and wavelength scanner have been dem onstrated.
