| Abstract: | The transmission and coupling properties of high peak power laser pulses in multimode fibers are investigated using Q-switched Nd:YAG pulsed laser. Laser damage threshold is measured. The maximum output laser energy density of 12J/cm with the width of 10ns and the maximum output laser energy of 3.5 J with the width of ms behind fibers are reached respectively, which can meet the uses of lasers in industry such as laser marking. |
