High-Energy Nanosecond Optical Vortex Output From Nd:YAG Amplifiers PROJECT TITLE :High-Energy Nanosecond Optical Vortex Output From Nd:YAG AmplifiersABSTRACT:Optical vortex amplification up to the joule level using flash-lamp-pumped Nd:YAG amplifiers has been demonstrated for the first time. In experiment, vortex seed pulses were converted from a typical -switched Nd:YAG laser output by a spiral section plate and amplified with 2 Nd:YAG amplifier stages. A most output energy of optical vortex up to 995 mJ has been achieved at 10 Hz in an exceedingly 10-ns pulse, such as an amplification factor of 295%. A most second-harmonic energy up to 470 mJ was generated from the amplified vortex output by using a KD*P crystal. The prospects of joule nanosecond vortex pulses generation by this approach were mentioned. Did you like this research project? To get this research project Guidelines, Training and Code...
