摘要：

We present a systematic study on the optimization of the following: 1) interpulse delay; 2) the pulse energies ratio; and 3) the combination of laser wavelengths to achieve the signal enhancement in double-pulse laser-induced breakdown spectroscopy (LIBS) on magnesium target using two Nd:YAG lasers in collinear configuration. More than 350 times signal intensity enhancement is achieved in the neutral magnesium lines on an appropriate combination of laser wavelengths with the optimized values of the interpulse delay and the laser pulse energies ratio.
