| contents | An upgraded high-energy nanosecond pulsed laser system tailored for optical particle diagnostics and manipulation capable of pulse energies beyond Joule-level is presented. In addition to the notable output energy increase, the laser system maintains its capability to generate laser pulses with customizable temporal profiles and variable durations ($1$ ns to $1$ $μ$s) along with a chirping range of several GHz over the pulse duration. The expanded output energy range is anticipated to greatly broaden the laser system's application potential, both for thermodynamic diagnostics via coherent Rayleigh-Brillouin scattering, by substantially lowering the particle density detection thresholds, as well as for particle manipulation, by facilitating more efficient optical trapping potentials for particle acceleration and deceleration. |
