Abstract: (2083 Views)
Characteristics of a special design optical configuration where consist of a white light LED-pumped Q-switched Ce:Nd:YAG laser oscillator and a four-pass blue light LED-pumped Ce:Nd:YAG optical amplifier is studied experimentally and calculated numerically. The results of calculations show that a 120 ns laser pulse in the range of 10-100 microjoules, after four pass and the amplifier initial gain coefficient 
, the gain is 1.3, that is consistent with the experimental observations. Moreover, the numerical results show that a seven-pass amplifier with two active medium increases the gain up to 1.6.
