The gain-switched operation of the semiconductor laser diode allows emission 
of optical pulses from 45 ps to 110 ps

        • Continuously tunable repetition rate from pulse-on-demand to 40 MHz

We will send a signal simultaneously to trigger the laser and to IST/FST 
readout system. We will need to tune the latency.
