Generation of a Synchronized Pulse of Extraordinary Precision Using Chirped Pulse Laser

Abstract

We have developed the generation system of synchronized pulses of high precision using chirped pulse laser. The PW laser is synchronized to Gekko XII beams within 10 picosecond by injecting part of the PW laser intc the Gekko XII laser system. A part of the 3ns/ 6nm (pulse width/ spectral width) output from the front end is stretched to 5.5ns/5nm and is then siliced to 1.1ns/nm width and injected into Gekko XII system. We have obtained 2.5-kJ output energy at a 532-nm wavelength from 12 semi-Gaussian beams. The pulse width is 1.1 ±0.1 ns (FWHM) and the conversion ef Hciency from 1 to 0.5mm was 43%.
