High-speed L-band wavelength-switchable active mode-locking pulsed fiber laser for photoacoustic microscopy

Abstract

In this work, we present an L-band wavelength-switchable nanosecond pulsed erbium-doped fiber laser using active mode-locking and multiple fiber-cavity length segments with fiber Bragg grating (FBG). It has pulse energy on the order of hundreds of nano-joules and switchable wavelengths of 1580 and 1600 nm. This laser can easily select a wavelength by modulating the mode-locking frequency determined by the cavity length of each wavelength. The pulse repetition rate can be tuned from 250 kHz to1 MHz, according to mode-locking order. To confirm the potential of the proposed laser for use in high-speed functional PAM, we successfully detected a PA signal from the pulse energy of 300 nJ with a PA signal detection system.
