Article Synopsis
- The Polaris laser system, a fully diode-pumped chirped-pulse amplification laser, achieved maximum energy pulses of 54.2 J before compression, with a spectral bandwidth of 18 nm at a wavelength of 1033 nm.
- Despite restrictions from the vacuum compressor, compressed pulses were achieved at 98 fs duration with an energy of 16.7 J, resulting in a peak power of 170 TW.
- The laser pulses exhibit an ultra-high temporal contrast, making them ideal for high-intensity laser-matter experiments.
We report on the first generation of high-contrast, 164 fs duration pulses from the laser system POLARIS reaching focused peak intensities in excess of 2×10(20) W/cm2. To our knowledge, this is the highest peak intensity reported so far that has been achieved with a diode-pumped, solid-state laser. Several passive contrast enhancement techniques have been specially developed and implemented, achieving a relative prepulse intensity smaller than 10(-8) at t=-30 ps before the main pulse.
