| Summary: | In this paper, a dual-wavelength synchronously
pulsed fiber laser Q-switched by carbon nanotube-based
saturable absorber with switchable wavelength spacing
enabled using arrayed waveguide grating (AWG) is proposed and demonstrated. By just switching the channels
of the AWG, discrete tuning in wavelength spacing of the
dual-wavelength Q-switched laser operation can be attained
over several nanometers, ranging from 1.6 to 4.0 nm in a
stable dual-wavelength regime without employing any
modulation technique or intracavity spectral filters. Our
experimental results show that the fiber laser can generate Q-switched microsecond pulses with a wide repetition
rate range, starting from 12.0 kHz to a maximum value of
54.9 kHz. This proposed system is also reasonably simple
to realize at low cost. |
