Wavelength-tunable picosecond burst-mode active mode-locking fiber laser for high-speed multispectral photoacoustic microscopy

Abstract

We proposed we proposed a novel wavelength-tunable picosecond burst-mode fiber laser based on the dispersive active mode-locking technique for high-speed multispectral photoacoustic microscopy. Using this configuration, rapidly wavelength tunning can be implemented in the broad region of 1030~1110 nm by changing the modulation frequency. After the output of the seed laser, a semiconductor optical amplifier (SOA) driven by the external programmable signal is employed for both optical amplification and pulse modulation. By providing an adjustable shaped burst of the ps-pulses train from the seed laser, this burst envelop can successfully act like a ns-pulsed laser required for PAM. We expect this new laser source to be widely used in real-time multispectral PAM applications.
