Frequency modulation optimization of nonlinear optical Z-scan by high repetition rate femtosecond laser
Nonlinear optical properties of 2- (2-hydroxyethyl)-6-(morpholin-4-yl) -1H-benzo[de]isoquinoline- 1,3(2H)- dione pigment material is investigated with frequency modulation of 250 MHz femtosecond high repetition rate (HRR) laser by an optical chopper. Thermal lensing formation on the material due to...
