STUDY OF OUTPUT ENERGY OF BIS-NICKEL PASSIVELY Q-SWITCHED Nd:YAG LASER

Abstract

A Bis-Nickel passively Q-switched Nd:YAG laser is experimentally studied. According to the obtained results for the laser output energy, we found that: (i) the laser output energy has a step by step behavior. (ii) In any step, the output energy has approximately constant value. (iii) The highest output energy is obtained from lowest initial transmission in this work. (iv) As the initial transmission decreases, the laser output energy increases. We deduced to increase the single pulse energy, a Q-switch with lower initial transmission should be used. Apparently, this behavior is true in the passive Q-switches.
