Q-switching of fibre lasers is an attractive means of converting the relatively low CW power of pump laser diodes into short, high intensity pulses for use in time-resolved sensor systems. Peak powers of 100W at 1.06µm with 15ms duration have previously been reported based on the use of Nd-doped alumino-silicate fibre as the gain medium. We report here the attainment of much higher powers in short pulses in a module specifically designed for high-resolution distributed sensor applications.
