*The first value is the delay set on the pulse generator; the second one is the actual delay. 
#We set this delay using the time difference between the YAG trigger and outgoing UV laser trigger. This  time difference is found to be slightly variable.  So I changed 291 delay from 202 to 201 to keep ~2us gate delay.
